Musannaf Ibn Abi Shaybah 17990 — A woman whose husband dies

Masruq (may Allah have mercy on him) and Amr bin Utbah (may Allah have mercy on him) wrote to Sayyidah Subay'ah bint al-Harith (may Allah be pleased with her), asking her about her case. She wrote back that she had given birth twenty-five days after the death of her husband. Then she made herself ready, seeking good. Sayyiduna Abu al-Sanabil bin Ba'kak (may Allah be pleased with him) passed by her and said: "You have been very hasty; observe the longer of the two waiting periods, that is, four months and ten days." Then she came to the Prophet (peace and blessings be upon him) and said: "O Messenger of Allah! Pray for forgiveness for me." The Prophet (peace and blessings be upon him) said: "What has happened?" She related the whole story, and the Prophet (peace and blessings be upon him) said: "If you find a good husband, then marry him."
