Musnad Ahmad 1153:2023

Ibn Abi ‘Adi narrated to us, from Dawud, from ‘Amir, who said: ‘Aisha said: "If the Messenger of Allah (peace and blessings of Allah be upon him) were to conceal anything of what was revealed to him by Allah, he would have concealed this verse regarding himself: 'And [remember, O Muhammad], when you said to the one on whom Allah bestowed favor and you bestowed favor, "Keep your wife and fear Allah," while you concealed within yourself that which Allah was to disclose and you feared the people, while Allah has more right that you fear Him' [Al-Ahzab: 37], up to His saying: 'And ever is the command of Allah accomplished' [Al-Ahzab: 37]."
