Ibn ‘Umar used to say, “A man’s kiss to his wife and his touching her with his hand are connected with sexual intercourse, and anyone who kisses his wife or touches her with his hand must perform ablution.”
Ubayy, Abu Talha and I sat and ate some meat and bread, after which I called for water to perform ablution. They asked, “Why are you performing ablution?” and I replied that it was because of this food which we had eaten. They said, “Do you perform ablution after eating things which are good? He who was better than you did not perform ablution on that account.”
