আল-আহযাব
And abide in your houses and do not display yourselves as [was] the display of the former times of ignorance. And establish prayer and give zakāh and obey Allāh and His Messenger. Allāh intends only to remove from you the impurity [of sin], O people of the [Prophet's] household, and to purify you with [extensive] purification.
Indeed, the Muslim men and Muslim women, the believing men and believing women, the obedient men and obedient women, the truthful men and truthful women, the patient men and patient women, the humble men and humble women, the charitable men and charitable women, the fasting men and fasting women, the men who guard their private parts and the women who do so, and the men who remember Allāh often and the women who do so - for them Allāh has prepared forgiveness and a great reward.
And [remember, O Muḥammad], when you said to the one on whom Allāh bestowed favor and you bestowed favor, "Keep your wife and fear Allāh," while you concealed within yourself that which Allāh is to disclose. And you feared the people, while Allāh has more right that you fear Him. So when Zayd had no longer any need for her, We married her to you in order that there not be upon the believers any discomfort [i.e., guilt] concerning the wives of their claimed [i.e., adopted] sons when they no longer have need of them. And ever is the command [i.e., decree] of Allāh accomplished.
