Ubaydullah bin Abdullah bin Utbah (may Allah have mercy on him) relates that his father (Abdullah bin Utbah (may Allah have mercy on him)) wrote to him that he should meet Sayyidah Subay'ah al-Aslamiyyah (may Allah be pleased with her) and ask her what judgement the Messenger of Allah (peace and blessings be upon him) had given in her case.
Ubaydullah (may Allah have mercy on him) relates: Malik bin Aws bin al-Hadathan (may Allah have mercy on him) informed me that Sayyidah Subay'ah al-Aslamiyyah (may Allah be pleased with her) told him that her husband, Sayyiduna Sa'd bin Khawlah (may Allah be pleased with him), died in Makkah while with the Messenger of Allah (peace and blessings be upon him) during the Farewell Pilgrimage, while she was pregnant; then only a short time after his death she gave birth. Abu al-Sanabil bin Ba'kak bin al-Sabbaq (may Allah be pleased with him) of Banu Abd al-Dar proposed marriage to her, but she refused to marry him. At this he said: "Know that you cannot become lawful for marriage until you complete the longer of the two waiting periods ('iddah)." So she asked the Messenger of Allah (peace and blessings be upon him) for a ruling on this, and he (peace and blessings be upon him) gave her permission to marry.
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Uqayl (may Allah have mercy on him) except the maternal uncle of Abu al-Tahir bin Sarh, Wathimah bin Musa bin Rabi'ah (may Allah have mercy on him)."
