The questioner : O Shaykh, regarding prayer in the cemetery.
The Shaykh : What?
The questioner : Prayer in the cemetery, O Shaykh.
The Shaykh : Yes.
The questioner : I do not know, the hadith, the hadith of the Black Woman.
The Shaykh : The Black Woman, and what is in it?
The questioner : The Messenger of Allah (peace and blessings be upon him) prayed at her grave.
The Shaykh : Ah.
The questioner : That the Messenger of Allah (peace and blessings be upon him) prayed at her grave.
The Shaykh : The funeral prayer is an exception to this, because it is restricted to a state in which it is unlikely that one would pray for the deceased, since he does not pray over him, unlike the usual prayer where one might imagine [praying toward the grave], so it is an exception.
