Al-Sha'bi (may Allah have mercy on him) narrates that he prayed the funeral prayer over Sayyidah Zaynab (may Allah be pleased with her) with Sayyiduna Umar (may Allah be pleased with him). She was the first of the wives of the Prophet (peace and blessings be upon him) to die. Sayyiduna Umar (may Allah be pleased with him) would have liked to lower her into her grave himself, so he sent word to the wives of the Prophet (peace and blessings be upon him): Who should lower her into her grave? They said: Whoever used to see her during her lifetime should lower her into her grave.
