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)
Sahih al-Bukhari Book 65, Hadith 436
← Previous Hadith I intended to ask `Umar about those two ladies who back each other against 'Allah's Messenger (ﷺ) . For one year I was seeking the opportunity to ask this question, but in vain, until once when I accompanied him for Hajj. While we were in Zahran, `Umar went to answer the call of nature and told me to follow him with some water for ablution. So I followed him with a container of water and started pouring water for him. I found it a good opportunity to ask him, so I said, "O chief of the Believers! Who were those two ladies who had backed each other (against the Prophet)?" Before I could complete my question, he replied, "They were `Aisha and Hafsa."

Sahih al-Bukhari Book 65, Hadith 435 Next Hadith → (regarding the Verse):-- 'Cruel after all that, base-born (of illegitimate birth).' (68.13) It was revealed in connection with a man from Quaraish who had a notable sign (Zanamah) similar to the notable sign which usually-hung on the neck of a sheep (to recognize it).
