The ruling on placing a marker on a grave and the manner of greeting the deceased

Question:
May Allah reward you, Honorable Shaykh. This questioner says: Is it permissible to place a marker on a grave so that I can come to it every so often to greet him? And what is the manner of greeting the occupant of the grave?

Answer:
Yes, it is permissible to place a marker on the grave, such as a stone or an iron rod driven into the ground, or a stick; that is, a marker that is not inscribed. It is not permissible to write on the grave or place a number on it; writing on it, whether letters or numbers, is not permissible. The Prophet (peace and blessings be upon him) forbade writing on graves. But something that only you know, such as a stone or something else, or a line in the ground that is not writing, there is nothing wrong with that. The Prophet (peace and blessings be upon him) placed a stone on the grave of Uthman ibn Maz'un in order to visit him, in order to pay him a visit. Yes.

Question:
Honorable Shaykh, this questioner says: I read in the magazine al-Da'wah

Answer:
As for greeting the deceased, they say it is like greeting a living person: you face his direction, you turn your back to the qiblah, you turn your back to the qiblah, and you face the deceased, so you are facing away from the qiblah and facing the deceased, just as you greet a living person, facing him directly, saying, "Peace be upon you, so-and-so, and the mercy of Allah and His blessings." Then you turn and stand at the grave facing the qiblah, then you make supplication for him and depart. When making supplication, you face the qiblah and place the grave between you and the qiblah. But when greeting, it is the opposite: you place the qiblah behind your back and face the deceased, and you greet him just as you greet a living person: "Peace be upon you, so-and-so, and the mercy of Allah and His blessings." Yes.
