Al-Ahzab 33:37 واذ تقول للذي انعم الله عليه وانعمت عليه امسك عليك زوجك واتق الله وتخفي في نفسك ما الله مبديه وتخشى الناس والله احق ان تخشاه فلما قضى زيد منها وطرا زوجناكها لكي لا يكون على المومنين حرج في ازواج ادعيايهم اذا قضوا منهن وطرا وكان امر الله مفعولا ٣٧

And ˹remember, O  Prophet,˺ when you said to the one¹ for whom Allah has done a favour and you ˹too˺ have done a favour,² “Keep your wife and fear Allah,” while concealing within yourself what Allah was going to reveal. And ˹so˺ you were considering the people, whereas Allah was more worthy of your consideration. So when Zaid totally lost interest in ˹keeping˺ his wife, We gave her to you in marriage, so that there would be no blame on the believers for marrying the ex-wives of their adopted sons after their divorce. And Allah’s command is totally binding.
