Is it a condition when burying a Muslim woman in the grave that the one who lowers her and the one who receives her should be of her Mahrams?

Q 2: Is it a condition when burying a Muslim woman in the grave that the one who descends with her and the one who receives her should be of her Mahrams (spouse or unmarriageable relative)?

A: It is not conditioned that the person who buries a Muslim woman in her grave should be a Mahram to her. It is narrated on the authority of Anas (may Allah be pleased with him): We witnessed the funeral of one of the daughters of the Messenger of Allah (peace be upon him) who was sitting by the side of the grave. I saw his eyes shedding tears. He (peace be upon him) said, 'Is there anyone among you who did not have conjugal relations with his wife last night?' Abu Talhah replied in the affirmative. And so the Messenger of Allah (peace be upon him) told him to get down in her grave and he got down in her grave and buried her. (Related by Al-Bukhari) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
