Yahya related to me from Malik that Ibn Shihab used to say, "Wudu is necessary if a man kisses his wife." Nafi said that Malik said, "That is what I like most out of what I have heard."
أَنَّهُ كَانَ يَقُولُ مِنْ قُبْلَةِ الرَّجُلِ امْرَأَتَهُ الْوُضُوءُ قَالَ ابْنُ نَافِعٍ قَالَ مَالِكٌ وَذَلِكَ أَحَبُّ مَا سَمِعْتُ إِلَىَّ
