Yahya related to me from Malik from Ibn Shihab from Salim ibn Abdullah that his father Abdullah ibn Umar used to say, "A man's kissing his wife and fondling her with his hands are part of intercourse. Someone who kisses his wife or fondles her with his hand must do wudu."
Muwatta Malik Book 2, Hadith 65
← Previous Hadith Yahya related to me from Malik from Nafi that Salim ibn 'Abdullah said, "I was with Abdullah ibn Umar on a journey and after the sun had risen I saw him do wudu and then pray. So I said to him, 'This isn't a prayer that you normally do. 'He said, 'After I had done wudu for the subh prayer, I touched my genitals. Then I forgot to do wudu. So I did wudu again and repeated my prayer.' "
