It is narrated from Sayyiduna Thawban (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Any woman who asks her husband for divorce without any (legitimate) harm or pressing need, Allah Almighty will forbid her (even) the fragrance of Paradise." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that in the blessed time of the Prophet (peace and blessings be upon him) a woman accepted Islam and (then) married (another man). Then her (first) husband came to the Messenger of Allah (peace and blessings be upon him) and said: I had accepted Islam together with her, and she knew of my accepting Islam. So the Messenger of Allah (peace and blessings be upon him) separated her from her second husband and returned her to the first husband. This hadith has a sahih chain of transmission, but the two Shaykhs did not record it. It is of the kind about which I say that Imam Bukhari used Ikrimah as evidence and Imam Muslim used Simak as evidence.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) returned his daughter Sayyidah Zaynab (may Allah be pleased with her) to her husband Abu al-As bin al-Rabi' on the basis of the first marriage itself, and did not do anything new (such as a new marriage contract or dower).
