At-Tahrim 66:1

Ya ayyuha annabiyyulima tuharrimu ma ahalla Allahu lakatabtaghee mardata azwajika wallahughafoorun raheem

O Prophet, why do you prohibit [yourself from] what Allāh has made lawful for you, seeking the approval of your wives? And Allāh is Forgiving and Merciful.

O Prophet, why do you ban (on your self) something that Allah has made lawful for you, seeking to please your wives? And Allah is Most-Forgiving, Very-Merciful.
