Narrated Anas: `Umar said, I agreed with Allah in three things, or said, My Lord agreed with me in three things. I said, 'O Allah's Messenger ! Would that you took the station of Abraham as a place of prayer.' I also said, 'O Allah's Messenger ! Good and bad persons visit you! Would that you ordered the Mothers of the believers to cover themselves with veils.' So the Divine Verses of Al-Hijab (i.e. veiling of the women) were revealed. I came to know that the Prophet had blamed some of his wives so I entered upon them and said, 'You should either stop (troubling the Prophet ) or else Allah will give His Apostle better wives than you.' When I came to one of his wives, she said to me, 'O `Umar! Does Allah's Messenger haven't what he could advise his wives with, that you try to advise them?' Thereupon Allah revealed:-- It may be, if he divorced you (all) his Lord will give him instead of you, wives better than you Muslims (who submit to Allah).. (66.5)
