Today I faced some ‘criticism’ from our brothers following the Sahaba (Companions) school of thought with regards to commemorating and remembering the birth of the Perfect Human and Mercy unto the Worlds, Prophet Muhammad (peace and blessings upon him and his pure family). My proofs were not good enough to completely convince them, so I suggested I would put some rational arguments forward, with main reference to verses from the Holy Qur’an. A decent book that counters such accusations (bid’ah, or innovations in religion, on the part of the followers of the Ahlul Bayt), is one by Ayatullah Ja’far Subhani’s ‘Wahabism‘, and in chapter 8 he tackles the issue of birth anniversaries:
‘The Wahhabis consider the honouring of birth and death anniversaries of awliya and divine personalities to be forbidden and an innovation. They are the staunch enemies of the awliya Allah and religious leadrs and consider the gatherings on their birth and death anniversaries to be (haram) prohibited.
Muhammad Hamid al-Faqi, the leader of group ‘Ansar al-Sunnat al-Muhammadiyya’ in his footnotes to his book al-Fath al-Majid writes:
“Remembering and celebrating on the days of birth and death of awliya amounts to one kind of worshipping them and respecting before them”. 
The root of all their mistakes is that because they have not determined any limit and margin for polytheism (shirk), tawhid and specially the meaning of ‘ibada, they think that every kind of respect and honour is worship. As you must have noticed, he has brought the word of ‘ibada and homage close to each other and imagines that both give the same meaning.
In the one of next chapters, we shall explain the meaning of ‘ibada and clearly prove that every honour and respect to the virtuous servants of God with the intention that they are the ‘servants’ of Allah, does not result in their worship at all. Therefore, we shall examine this discussion from another angle (not polytheism in ‘ibada).
Undoubtedly, Qur’an has repeatedly praised the Prophets and awliya with eloquent and rhetorical words.
About Zakaria, Yahya and others the Qur’an says:
“Surely they used to hasten, one with another, in deeds of goodness and to call upon Us, hoping and fearing, and they were humble before Us.” (al-‘Anbiya: 90) .
Now, if in a gathering which is held under their name, someone portrays them in a similar manner which has come down in the contents of this verse and by this way honours them, has he done anything other than obeying the Holy Qur’an?
About the household of the Prophet, Allah (swt) says:
"And they give food out of love for Him to the poor and the orphan and the captive." (Dahr: 8)
Now if the followers of Ali come together on the birthday of Amir al-mu’minin and say that Ali is one who used to give his own food to the poor, orphan and the captive, have they by this act worshipped him!?
If on the birthday of the Holy Prophet (s) we translate the verse which praises the Prophet into a non-Arabic language or write a poem on a tablet and recite it in a gathering, have we committed a forbidden action!?
They are having enmity with the matter of honouring the Holy Prophet (s) and awilya Allah that they wish to stop this under the pretext of fight against innovation.
At this stage a question is brought up to which the loud-speakers amongst the Wahhabis lay great emphasis and it is this: ‘Since these assemblies and gatherings are held under the name of religion and are labelled as Islamic, they should be approved specifically and generally by the Islamic rules. Otherwise it would be innovation (bid’at) and forbidden (haram).
The reply to this question is quite clear because the verses of Qur’an that draw our attention to the necessisty of honouring the Prophet is sufficient in this case and these kinds of gatherings are not held for any reason other than respecting the awliya Allah. That thing is considered to be ‘innovation’ which is not approved specifically or generally by Qur’an or the Sunnah of the Holy Prophet.
The purpose of these honourings which is common amongst all the nations of the world is nothing but paying respect and homage and this practise is common among all the Muslims of the world except for these handful of dry wahhabi ‘Najdis’. If it was innovation and something new and not confirming with the general Islamic principles, it was impossible that the Islamic scholars would celebrate the birthday of the Holy Prophet (s) and make splendid such gatherings by reading scholarly monographs and reciting sweet and elegant poems.
Here are some logical reasonings from Qur’an permitting such respect and honourings:
The Holy Qur’an praises that group of people who honour the Holy Prophet (s):
“So (as for) those who believe in him and honour him and help him, and follow the light which has been sent down with him, these it is that are the successful.” (A’raf: 157)
The words which have appeared in this verse comprises of:
Is it possible for one to think that the words ,and are confined to the period of the Holy Prophet? Certainly not! If such a probability cannot be given about these three words, the word of which gives the meaning of honour and respect  cannot be assigned to the period of the Holy Prophet (s) and thus this sublime leader should be respected and honoured at all times.
Is it not that arranging memorial gathering on the day of bi’that and birth of the Holy Prophet (s) and delivering speeches and poems on such occasions clear evidence to ?
Surprisingly, the Wahhabis pay homage and respect their own tribal leaders and rulers and honour even one ordinary person such that observing one hundredth of that with regard to the Holy Prophet (s), his pulpit and alter is considered to be innovation and anti-Islamic by them. As a result they introduce Islam to the world as one dry religion lacking any sentiments and affections and think that the shari’a which is in fact simple and easy, matching with the human nature and feeling and generous enough to attract the people is a dry "shari’a" which does not consider the respect of divine leaders to be of any significance and does not possess the ability to attract the people of the world.
What do the Wahhabis who oppose any kind of mourning ceremonies for the martyrs in the way of Allah have to say about the story of Ya’qub (‘a)? If today, this great Prophet was living amongst these Najdis and the followers of Muhammad bin ’Abd al-Wahhab how would have they judged him?
Day and night he was weeping for his separation from Yusuf and all the time he was asking the people about the whereabouts of his beloved son. He was so much sorrowful by the separation of his son that he lost his eye-sight. 
Sickness and loss of eye-sight did not deter Ya’kub (‘a) from forgetting his son Yusuf (‘a). Instead, as the promise of re-union was drawing closer the flames of love towards his son increased manifold and he could smell Yusuf miles away. 
And instead of the star (Yusuf) pursuing the sun (Ya’qub (‘a)) it was vice -versa.
Why expression of such affection during the life of the loved one (i.e. Yusuf) is correct and confirms to Tawhid but after his death when the heart becomes more prone to pain and suffering it amounts to polytheism and becomes forbidden?
Now if the Ya’qubs of our time gather together every year on the death anniversary of their Yusufs and speak about the value of his moral qualities due to which they start crying, will such an act amount to worshipping of their sons!? 
Undoubtedly, (love towards kinship) is one of the Islamic obligations which Qur’an explicitly commends us towards it. Now, after fourteen centuries if someone wishes to act upon the religious obligations then what should we do? Is it not that he should rejoice on their joyous days and become sorrowful on the days of their grief and sorrow?
Now, for expressing one’s own pleasure, if someone holds a gathering wherein he reveals their historical life and sacrifices and describes their innocence and their deprivation from their rightful claims then, has he done anything other than expressing his affection and manifesting mawadda dhawi’l qurba? ( )
If, for showing more affection, such a person visits their progeny and comes near their graves and holds such gatherings near their graves then, has he in the eyes of the wise and intelligent people, done anything other than manifesting his love and affection!?
Except that the Wahhabis may say: Such love and affection should be kept secret and confined to the heart and no one has the right to manifest and express them (openly).
During the time of the Holy Prophet (s) and the period after him which was the period of change of thoughts and beliefs, different tribes and nations with different cultures and customs were turning towards Islam and by reciting the shahadatayn (creed) their Islam was accepted. The position of Prophet and the leaders was never to investigate, censor (by establishing the ‘section for scrutinizing of beliefs’) than dissolve the entire rites and customs of the nations and tribes and bring them out in another form different from the previous ones.
Respect of leaders, establishing memorial ceremonies, attending the graves and expressing love for their signs and traces was and is the custom of all nations and tribes. At present too, the people of East and West stand for hours in que waiting to pay visit to the mummified bodies and graves of ancient leaders in order to express their love and shed tears in their grief. They consider this to be one way for expressing respect and honour.
It was never seen that the Holy Prophet (s) would accept the Islam of people only after investigating their beliefs and examining their practises and customs in practical life. Instead, expressing the ‘Shahadatain’ was enough for him. If these practices and customs were forbidden and or amounted to worshiping the ancestors, then it was necessary to accept the Islam of nations and tribes (only) after taking allegiance and promise from them about their exoneration (of such practices) while such was never the case.
We see Isa (‘a) asks for table (with food) from the Almighty Allah and introduces the day of its descension as the day of celebration and says:
“O Allah, our lord! send down to us food from heaven which should be to us an ever-recurring happiness, to the first of us and the last of us, and a sign from Thee, and grant us means of subsistence, and Thou art the best of the Providers.” (Maida: 114)
Is the value of the Holy Prophet’s existence lesser than one heavenly table which Isa (‘a) declares the day of its descension to be the day of ‘Eid’. If such a day is declared to be the day of ‘Eid’ because of the table being a divine sign, then is not the Holy Prophet (s) the greatest divine sign!?
Woe to those who are ready to celebrate the day of descension of one heavenly table that feeds the stomachs but ignore and label as innovation, the celebration of the day of descension of Qur’an and the day of appointment (bi’that) of Prophet who blessed the minds of human beings with perfection of thought over the period of history !
The Qur’an says:
“And exalted for you your esteem”? (Inshiraah: 4)
Is it that arranging gatherings for celebrating the days of birth of the Holy Prophet (s) having any purpose other than elevating his name and fame! Why in this case we should not follow the Qur’an? Is not Qur’an an example and the best model for us?
 al-Fath al-Majid, page 154. At this time when these pages and papers are being composed, and in the entire Islamic countries celebrations are being held on the occasion of the birth of the Holy Prophet, the Mufti of the House of Sa’ud, Bin Baz has declared as forbidden and innovation any kind of respect for the birthday of the Holy Prophet (s). But the same person addressed King Faisal al-Sa’ud during his reign as ‘Amir al-mu’minin’ and this action was biting and shocking to the extent that the king too understood and excused for accepting this title.
