Quran 33:37
quran
37 When thou saidst to him whom God had blessed and thou hadst favoured, 'Keep thy wife to thyself, and fear God,' and thou wast concealing within thyself what God should reveal, fearing other men; and God has better right for thee to fear Him. So when Zaid had accomplished what he would of her, then We gave her in marriage to thee, so that there should not be any fault in the believers, touching the wives of their adopted sons, when they have accomplished what they would of them; and God's commandment must be performed.
This verse was cited in the Zayd and Zaynab discussion to argue that revelation abolished adoption rules in order to justify Muhammad marrying his adopted son's former wife.
Wood cited this verse to discuss Muhammad's marriage to Zaynab, presenting it as another case of revelation serving Muhammad's personal desires.
