It may be, if he divorced you (all), that his Lord (Allah) will give him instead of you, wives better than you... (V.66:5)

The wives of the Prophet (ﷺ) out of their jealousy, backed each other against the Prophet, so I said to them, "It may be, if he divorced you all, that Allah will give him, instead of you wives better than you." So this Verse was revealed. (66.5)
