A Grieving Mother: Is It Permissible to Dedicate the Reward of Her Dhikr and Fasting on Noble Days to Her Deceased Son? What Is the Ruling on Her Action?

Question:
In her second-to-last question, she says: When I pray, I recite after the prayer , and there is no god but Allah alone, with no partner, to Him belongs dominion and to Him belongs praise, and He is over all things competent, completing one hundred times. And I say: O Allah, make its reward for my deceased son. What is the ruling on that? And likewise regarding fasting on the Day of 'Arafah, where I fast it, then I say: O Allah, make its reward for my deceased son. What is the ruling on that? May Allah reward you.

Answer:
This has not been reported from the Prophet (peace and blessings be upon him) that he dedicates that he dedicates the dhikr after the obligatory prayers to the deceased or others. This has not been reported from the Prophet (peace and blessings be upon him). Rather, what has been reported is to seek forgiveness for them, to supplicate for them with mercy and forgiveness, to give charity on their behalf, and to perform Hajj or 'Umrah on their behalf. This is what has been reported from the Prophet (peace and blessings be upon him), and in such matters, one restricts oneself to what has been reported and does not add to it. Yes.
