Sa'd bin Ishaq bin Ka'b bin Ujrah narrates from his paternal aunt Zaynab bint Ka'b (may Allah be pleased with her) that Furay'ah bint Malik bin Sinan (may Allah be pleased with her) informed her that she came to the Prophet (peace and blessings be upon him) and asked him (peace and blessings be upon him) about returning to her family (Banu Khudrah), and that her husband had gone out in search of slaves of his who had run away; when they were at the edge of al-Qadum, he caught up with them, and they killed him. I asked the Messenger of Allah (peace and blessings be upon him): "May I return to my family? My husband did not leave me in a dwelling that he owned." She said: The Messenger of Allah (peace and blessings be upon him) said: "Yes, you may return." I turned away, until, when I was in the chamber or in the mosque, I was called, or an order was given concerning me, and I was summoned to him (peace and blessings be upon him). He (peace and blessings be upon him) asked: "What do you say?" I repeated to him (peace and blessings be upon him) the story I had mentioned about my husband, and he (peace and blessings be upon him) said: "Stay in your house until your waiting period is completed." She said: So I observed (the waiting period) in it for four months and ten days. When Sayyiduna Uthman (may Allah be pleased with him) sent a messenger to me and asked me about that, I informed him, and he followed it and judged according to it.
