The custom of instructing the deceased at burial and reciting the Qur'an over his grave: Does it have a basis in the Shari'ah?

Question:
May Allah reward you and make your knowledge beneficial. The listener, the listener Muhammad Muhammad Ibrahim from the Hodeidah in the Yemeni Republic sent three questions. In the first, he says: Some of the jurists among us (may Allah guide them) have the custom, after finishing the burial of the deceased, for the jurist to sit at the head of the deceased and begin reciting. He starts by reciting the words of Allah the Exalted: "Every soul " Then he recites Surat al-Ikhlas and the two protective surahs, then Surat al-Fatihah. When he reaches the words "nor those who go astray," the people present say "Ameen" aloud with him. Then he recites the words of Allah the Exalted: . Then he says to the deceased: "May Allah firm you with the firm word," three times. Then he says to him: "If the two angels assigned to you come and ask you, 'Who is your Lord and who is your Prophet?' say to them: 'Allah is my Lord, Muhammad is my Prophet, the Ka'bah is my qiblah, and the believers are my brothers,'" twice. Is this action permissible? And what is your guidance? May Allah reward you.

Answer:
This entire action has no basis. The hadith regarding instructing the deceased after burial is weak; in fact, some scholars consider it fabricated. It does not serve as a proof. The only prescribed practice, which the Prophet (peace and blessings be upon him) commanded, is that when they finish burying the deceased, they stand over his grave, seek forgiveness for him, and ask Allah to firm him, as the Prophet (peace and blessings be upon him) said:
This benefits him, with the permission of Allah. As for reciting the Qur'an at the head of the grave, and as for instructing the deceased after burial, all of this has no basis.
