Fataawa al-Lajnah ad-Daa.imah lil-Buhooth al-‘Ilmiyyah wal-Iftaa. – Fatwa No.3582
Question: On the last night of the Blessed month of Ramadhaan, year 1400 A.H (1979 A.D), the imaam led the congregation and completed the [recitation of the entire] Qur’aan and said: “The completion [of the recitation] of this Qur’aan is gifted to the soul of our master, our leader and our Prophet Muhammad, the pure”. What is the Sharee’ah ruling regarding this?
Response: It is not permissible to gift [any] reward to the Messenger (sal-Allaahu ‘alayhi wa sallam), neither the completion [of the recitation] of the Qur’aan or other than this. This is because the Pious Predecessors from the companions (radhi-yAllaahu ‘anhum) and those after them did not do this since acts of worship are towqeefiyyah. He (sal-Allaahu ‘alayhi wa sallam) said:
«Anyone who does an act which is not in agreement with us, then he will have it rejected» – narrated by Muslim.
The Prophet (sal-Allaahu ‘alayhi wa sallam) receives the same reward for all righteous acts done by his Ummah because he is the one who invited and showed the way to them. It has been authenticated on his (sal-Allaahu ‘alayhi wa sallam) authority that he said:
«Whoever directs to [something that is] good, then for him is the reward equal to the one having done it (this good act)» Muslim reported it in his Saheeh from the hadeeth of Abu Mas’ood al-Ansaaree.
And with Allaah lies all success and may Allaah send prayers and salutations upon our Prophet (sal-Allaahu ‘alayhi wa sallam) and his family and his companions.
