Can a dead person benefit from

Q 2: Is it permissible to give a Sadaqah (voluntary charity) and grant the reward thereof for a dead person who passed away three, seven, or forty days ago?

(Part No. 9; Page No. 29)  A: It is absolutely Mashru` (Islamically acceptable) to give Sadaqah and grant its reward for a dead Muslim person at any time without it being restricted to any period of three, seven, or forty days after his death. This is because Sunnah (whatever is reported from the Prophet) ordains giving Sadaqah and granting its reward for the dead without mentioning any specific day after the date of death.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
