Reciting Al-Fatihah with the intention of invoking Allah's Mercy on my deceased paternal aunt and her deceased son

Q 3: The Messenger of Allah (peace be upon him) said: When a person dies, their works (righteous acts) come to an end, except for three: Sadaqah Jariyah (ongoing charity), beneficial knowledge, or a pious child who supplicates for them. Is it permissible to recite Al-Fatihah (Opening Chapter of the Qur'an) with the intention of invoking Allah's Mercy on my deceased uncle and his deceased son? If it is not permissible, what are the appropriate supplications in such situations?

A: It is not permissible to recite Al-Fatihah or any other portion of the Qur'an for the deceased, for lack of evidence on this issue. The Prophet (peace be upon him) said: Anyone who does an action which is not in accordance with this matter of ours (Islam) will have it rejected. (Related by Muslim) Yet, you can give Sadaqah (voluntary charity) on their behalf and supplicate Allah (Exalted be He) to forgive and have mercy on them and admit them to Paradise and protect them from Hellfire. May Allah guide us and you to every good path.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
