Do not tell anyone of that.” 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.
One makes atonement for something he has made unlawful for himself.* You have had a good example in God’s Messenger.
* i.e. something not in itself unlawful. It is treated like an oath for breaking which atonement must be made. The Prophet’s example refers to his withdrawing from his wives for a period.
