Sahih al-Bukhari Book 68, Hadith 69
Subai'a Al-Aslamiya gave birth to a child a few days after the death of her husband. She came to the
Prophet and asked permission to remarry, and the Prophet (ﷺ) gave her permission, and she got married.
that his father had written to Ibn Al-Arqam a letter asking him to ask Subai'a Al-Aslamiya how the Prophet had given her the verdict. She said, "The Prophet, gave me his verdict that after I gave birth, I could marry."
that Yahya bin Sa`id bin Al-`As divorced the daughter of `Abdur-Rahman bin Al-Hakarn. `Abdur- Rahman took her to his house. On that `Aisha sent a message to Marwan bin Al-Hakam who was the ruler of Medina, saying, "Fear Allah, and urge your brother) to return her to her house." Marwan (in Sulaiman's version) said, "Abdur-Rahman bin Al-Hakam did not obey me (or had a convincing argument)." (In Al-Qasim's versions Marwan said, "Have you not heard of the case of Fatima bint Qais?" Aisha said, "The case of Fatima bint Qais is not in your favor.' Marwan bin Al-Hakam said to `Aisha, "The reason that made Fatima bint Qais go to her father's house is just applicable to the daughter of `Abdur-Rahman."
