It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "When a slave marries without the permission of his master, he is a fornicator ('ahir)." This hadith is sahih (authentic) in its chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Buraydah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said to Sayyiduna Ali (may Allah be pleased with him): "O Ali, do not follow one glance with another, for the first glance is (forgiven) for you, but you have no right to the second." This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abu al-Darda' (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) was on a military expedition, and he (peace and blessings be upon him) saw a woman who was pregnant (close to giving birth). He (peace and blessings be upon him) asked: "Perhaps her owner has had relations with her?" The people said: "Yes." He (peace and blessings be upon him) said: "I was minded to curse him with a curse that would enter his grave with him. How can he make him (the child) his heir when that is not lawful for him, and how can he take service from him when that is not lawful for him? (That is, because of intimacy before the waiting period of istibra', doubt has arisen over the lineage of the child born.)" 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 Abu Sa'id al-Khudri (may Allah be pleased with him), attributing it to the Prophet (marfu'), concerning the captive women of the Battle of Awtas, that he (peace and blessings be upon him) said: "A pregnant woman is not to be approached until she gives birth, and one who is not pregnant (is not to be approached) until she has had one menstrual period (so that it is certain the womb is empty)." This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: Ibn Umar (may Allah forgive him) was mistaken in this matter. The actual story is that this tribe of the Ansar were idol-worshippers and lived alongside the Jews, who were People of the Book. The Ansar acknowledged their (scholarly) superiority and followed them in many of their practices. The way of the People of the Book was to approach women only from one side (lying on the side), which was the most modest position for a woman, and the Ansar had adopted this practice from them. On the other hand, the Quraysh used to enjoy women lying on their backs, from the front, from behind and in various ways. When the Muhajirun came to Madinah, a man among them married a woman of the Ansar and wanted to do the same with her, but she firmly refused and said: "We have been accustomed only to one particular side (for intimacy). Either you do the same, or keep away from me." Eventually their matter became serious and reached the Messenger of Allah (peace and blessings be upon him). Then Allah Almighty revealed this verse: 'Your wives are a tilth for you, so come to your tilth however (from whichever direction) you wish' [Surah al-Baqarah: 223] , meaning whether from the front, from behind or lying on the back, provided that what is meant is the place of childbirth (the private part). This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs did not record it with this wording; they agreed upon the hadith of Jabir (may Allah be pleased with him) on this topic. This is the end of the Book of Marriage and the beginning of the Book of Divorce.
