460. This matter is controversial; the best argument for the above position is what Imam Ibn al-Qayyim (may Allah bestow mercy on him) said: Worship is of two types: financial and bodily. When the Legislator informed us that the reward for charity reaches the dead, He indicated that the reward for financial acts of worship reaches them, and when he informed us that the reward for fasting reaches the dead, He indicated that the reward of bodily acts of worship reaches them. He also informed us of the reaching of the reward of Hajj, which is both a financial and bodily act of worship. Thus, these three types [of acts done by the living for the benefit of the dead] are supported by both the revealed texts and reason.
This includes the reading of Qur’an. This is the position of (A) + (+H, +m, +s, +t). As for gathering to recite the Qur’an and grant the reward to the deceased, this particular form has not been reported from the Prophet (SA) and his Companions, but Imam Ibn Qudâmah said in al-Mughni that “Muslims throughout the different lands and ages used to gather and recite the Qur’an for the deceased without condemnation.” Therefore, those who regard the act as innovated may abstain from it, but they should not condemn those who regard it permissible, because there is a scholarly disagreement.
(A) + (+H, +M, +S): The only exception is that the mandatory prayers are not prayed on behalf of the deceased. If someone offers a mandatory prayer, they may not give away its reward to anyone else. Finally, the things that reach the deceased, by agreement, are supplications and charity, so these are the most encouraged.
