Verse 37

وَإِذْ تَقُولُ لِلَّذِىٓ أَنْعَمَ ٱللَّهُ عَلَيْهِ وَأَنْعَمْتَ عَلَيْهِ أَمْسِكْ عَلَيْكَ زَوْجَكَ وَٱتَّقِ ٱللَّهَ وَتُخْفِى فِى نَفْسِكَ مَا ٱللَّهُ مُبْدِيهِ وَتَخْشَى ٱلنَّاسَ وَٱللَّهُ أَحَقُّ أَن تَخْشَىٰهُ فَلَمَّا قَضَىٰ زَيْدٌ مِّنْهَا وَطَرًا زَوَّجْنَـٰكَهَا لِكَىْ لَا يَكُونَ عَلَى ٱلْمُؤْمِنِينَ حَرَجٌ فِىٓ أَزْوَٰجِ أَدْعِيَآئِهِمْ إِذَا قَضَوْا۟ مِنْهُنَّ وَطَرًا وَكَانَ أَمْرُ ٱللَّهِ مَفْعُولًا

And when you said to the one that God had blessed and you had blessed; stay with your wife and fear God and you kept inside you what God wanted to declare and you feared people when fearing God was the right thing to do, therefore once Zaid was through with her, We made you marry her in order to show that the faithful commit no error by marrying the wives of their adopted sons when they are finished with them. And God’s command shall be carried out.
