At-Taḥrīm (, "Banning, Prohibition") is the 66th Surah or chapter of the Quran and contains 12 verses (ayah). This Surah deals with questions regarding Muhammad's wives. The Surah's name is derived from the words lima tuharrimu of the first verse. This is not a title of its subject matter, but the name implies that it is the Surah in which the incident of tahrim (prohibition, forbiddance) has been mentioned. Summary 1 Muhammad reproved for making a vow to please his wives 2 He is relieved from his vow 3-5 Muhammad's wives(Aisha & Hafsa) reproved and threatened for their jealousy in the affair of Zaynab bint Jahsh, Muhammad's another wife 6-8 Exhortation to believers to exercise faith, repentance etc. 9 Muhammad commanded to treat infidels and hypocrites with severity 10-12 The wives of Noah, Lot, Pharaoh, and the daughter of Imran examples to Muslim women Probable date of revelation In connection with the incident of Tahrim referred to in this Surah, the traditions of the Hadith mentions the affair regarding the three ladies who were among the wives of Muhammad at that time; Safiyya bint Huyayy, Zainab Bint Jahsh and Maria al-Qibtiyya. The former (i. e. Safiyyah) was taken to wife by Muhammad after the conquest of Khaiber, and Khaiber was conquered, as has been unanimously reported, in A. H. 7. The other lady, Mariyah, had been presented to Muhammad by Al-Muqawqis, the ruler of Egypt, in A. H. 7, whom Muhammed had known to freed and married her according to Ibn Kathir and had borne him his son, Ibrahim ibn Muhammad, in Dhu al-Hijjah, A. H. 8. Another Hadith tradition mentions about the honey incident which have been known to take place in A. H. 8. These historical events almost precisely determine that this Surah was sent down some time during A. H. 7 or A. H .8. Asbab al-nuzul Asbāb al-nuzūl, an Arabic term meaning "occasions/circumstances of revelation", is a secondary genre of Qur'anic exegesis (tafsir) directed at establishing the context in which specific verses of the Qur'an were revealed.
