We are told in this Hadith that two angels question man in the grave. Allah helps a true believer in answering correctly. He says to the angels, "Allah is my Rubb. Islam is my religion. And the man sent by Allah as His Prophet is Muhammad." A condemned person will say, "Aa, Aa, I do not know." We are, therefore, particularly instructed that after the burial of a fellow-Muslim, we should supplicate beside his grave for his being firm-footed against the ordeal to which he will be subjected.
