Dawud reported on the same authorities the hadith as narrated above by Ibn 'Uliyya and added: She ('A'isha) said: If Muhammad were to conceal anything which was sent to him, he would have certainly concealed this verse:" And when thou saidst to him on whom Allah had conferred favour and thou too had conferred favour: Keep thy wife to thyself and fear Allah, and thou wast concealing in thy heart that which Allah was going to disclose, and thou wast fearing men while Allah has a better right that thou shouldst fear Him."
