Sahih Muslim 177b

Muhammad ibn al-Muthanna narrated to us: 'Abd al-Wahhab narrated to us: Dawud narrated to us with this chain, reporting a hadith similar to that of Ibn 'Ulayya. He added: 'A'isha said, “If Muhammad (peace and blessings be upon him) had concealed anything that was sent down to him, he would have concealed this verse: ‘And when you said to the one to whom Allah had shown favor, and to whom you had shown favor, “Keep your wife and fear Allah,” while concealing within yourself what Allah would disclose, and fearing the people, though Allah has more right that you should fear Him.’”
