What is the ruling on gathering to recite the Du`a' (supplication) after memorizing the Noble Qur'an i.e. when a person has finished reading the Qur'an he calls his family or other people to offer Du`a' together for having completed the Qur'an this Du`a' is attributed to ShaykhulIslam Ibn Taymiyyah (may Allah have mercy on him) so that they will all receive the reward for completing the Qur'an, or other Du`a's written at the end of the Mushaf and called "Du`a' Khatm alQur'an al`Azim (supplication for finishing the Noble Qur'an)"? Is it permissible to gather to recite Du`a' for completing the Noble Qur'an, whether at the end of Ramadan or on other occasions? Is this gathering counted as Bid'ah (innovation in religion)? Has any Du`a' specifically prescribed for finishing the Noble Qur'an that is narrated from the Messenger of Allah (peace be upon him)? Please explain this issue in detail. Could you kindly substantiate your view?
As far as we know, there is no evidence of any specific Du`a', so it is permissible for a person to pray for whatever he wants and to choose any good Du`a', such as asking for forgiveness of sins or to be granted Paradise and be saved from Hell, or to seek refuge from tribulation, or to be granted help to understand the Qur'an in the way that pleases Allah (Exalted be He) and to act in accordance with it, and so on. It is reported that Anas (may Allah be pleased with him) used to gather his family when he finished reading the Qur'an to offer Du`a'. With regard to the Prophet (peace be upon him), nothing to this effect was narrated from him as far as I know.
As for the Du`a' attributed to ShaykhulIslam Ibn Taymiyyah (may Allah have mercy on him), I do not know whether this attribution is correct or not. Though it is circulated among our Sheikhs as well as other Sheikhs, I have never come across anything of that sort in his books. Fianlly, Allah knows best.
