A'isha said:The Prophet used to spend time with Zainab daughter of Jahsh and that he once drank honey at her house, so Hafsa and she agreed that the one whom the Prophet visited first should say,“I notice that you have an odour of the gum of the mimosa.* Have you eaten some?”When he visited one of them and she said that to him he replied,“Don’t worry; I drank some honey at the house of Zainab daughter of Jahsh, but I swear that I shall not do it again. Do not tell anyone of that.” [He said this] desiring to please his wives, and then there came down,“O prophet, why do you hold to be forbidden what God has made lawful for you, desiring to please your wives? (Al-Qur’an 66:1). *Maghafir; plural of Mughfur, is here used. It is the gum of a kind of mimosa called ‘urfut, the odour of which is unpleasant. (Bukhari and Muslim.)
