Sahih Al Bukhari (402)

قال عمر: وافقت ربي في ثلاث: فقلت: يا رسول الله، لو اتخذنا من مقام إبراهيم مصلى، فأنزلت: {وَاتَّخِذُوا مِنْ مَقَامِ إِبْرَاهِيمَ مُصَلًّى} [البقرة: 125]. وآية الحجاب، قلت: يا رسول الله، لو أمرت نساءك أن يحتجبن، فإنه يكلمهن البر والفاجر، فنزلت آية الحجاب، واجتمع نساء النبي صلى الله عليه وسلم في الغيرة عليه، فقلت لهن: عسى ربه إن طلقكن، أن يبدله أزواجا خيرا منكن، فأنزلت هذه الآية.

`Umar (ibn Al Khattab) (may Allah be pleased with him) narrated: My Lord agreed with me in three things: 1. I said, “O Allah’s Messenger, I wish we took the station of Abraham as our praying place (for some of our prayers). So came the Divine Inspiration: And take you (people) the station of Abraham as a place of prayer (for some of your prayers e.g. two Rak‘at of Tawaf of Ka‘ba)”. 2. And as regards the (verse of) the veiling of the women, I said, ‘O Allah’s Messenger! I wish you ordered your wives to cover themselves from the men because good and bad ones talk to them.’ So the verse of the veiling of the women was revealed. 3. Once the wives of the Prophet (peace be upon him) made a united front against the Prophet (peace be upon him) and I said to them, ‘It may be if he (the Prophet (peace be upon him)) divorced you, (all) that his Lord (Allah) will give him instead of you wives better than you.’ So this verse (the same as I had said) was revealed.”
