Malik Muwatta: Hadith 664

Yahya related to me from Malik from Zayd ibn Aslam from Ata ibn Yasar that a certain man kissed his wife while he was fasting in Ramadan. This made him very anxious, and so he sent his wife to the Prophet (ﷺ) to ask him about that for him. She went in and saw Umm Salama, the wife of the Prophet (ﷺ) and mentioned the matter to her, and Umm Salama told her that the Messenger of Allah (ﷺ) used to kiss while he was fasting. So she went back and told her husband that, but it only made him find fault all the more and he said, "We are not like the Messenger of Allah (ﷺ). Allah makes permissible for the Messenger of Allah (ﷺ) whatever He wishes."

His wife then went back to Umm Salama and found the Messenger of Allah (ﷺ) with her. The Messenger of Allah (ﷺ) said, "What's the matter with this woman?", and Umm Salama told him. The Messenger of Allah (ﷺ) said, "Didn't you tell her that I do that myself?" and she said, "I told her, and she went to her husband and told him, but it only made him find fault all the more and say, 'We are not like the Messenger of Allah (ﷺ). Allah makes permissible for His Messenger, may Allah bless him and grant him peace, whatever He wishes.' " The Messenger of Allah (ﷺ) got angry and said, "By Allah, I am the one with the most taqwa of Allah of you all, and of you all the one who best knows His limits."
