Granting the reward of Salah to a deceased person

A: It is impermissible to grant the reward of your Salah (prayer) to the dead, for it is a Bid`ah (innovation in religion). This is so because this has not been authentically reported from either the Prophet (peace be upon him) or the Sahabah (Companions of the Prophet, may Allah be pleased with them). The Prophet (peace be upon him) said: Anyone who introduces anything into this matter of ours (Islam) that is not part of it will have it rejected. Related by Al-Bukhari and Muslim .
