Sayyiduna A'idh bin Amr (may Allah be pleased with him) says: I was with the Prophet (peace and blessings be upon him) on a military expedition. When we were returning to Madinah, a woman whose husband had been martyred with the Messenger of Allah (peace and blessings be upon him) began to weep. He (peace and blessings be upon him) said: "Who is this weeping woman?" The people said: She is Fatimah bint Adi. He (peace and blessings be upon him) said: "Your affair is entrusted to A'idh bin Amr." So A'idh (may Allah be pleased with him) married her to his father and charged him to take care of her.
