Q: We have
a Mushaf (copy of the Qur'an) at the Administration of Education in Shaqra' and on the back cover page of the Mushaf there is
a supplication which reads as follows: 'O Allah, send the reward of what we have recited to the soul of Muhammad (peace be upon him) and other souls'. According to what has been mentioned on P. 524 attached with these questions, and according to what some people in our administration say, it is not permissible to give the reward of recitation to the souls of the dead. Please advise; should we use it or not and only read the supplication for the reciter without the souls of the dead?
It is not permissible to use these words either at the end of (Part No. 2; Page No. 233) recitation or in any act, because it is not authentically reported from the Prophet (peace be upon him). It is an innovated supplication and the Prophet (peace be upon him) stated:
Anyone who does an action which is not stated in this matter of ours (Islam) will have it rejected.
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
