Abu Huraira, Ibn Mas'ud and Ibn ‘Umar reported the Prophet as saying, “He who performs ablution and mentions God’s name purifies his whole body, but he who performs ablution and does not mention God’s name is pure only where the ablution reached.”
Abu Huraira reported God’s messenger as saying, "If one lies on his wife and compresses her, washing is necessary, even if he does not insert his penis.”
‘Abdallah b. ‘Amr b. al-‘As said that the Prophet came upon Sa'd when he was performing ablution and asked, “What is the meaning of this extravagance, Sa'd?” He replied, “Is there extravagance in ablution?” He said, “Yes, even if you are beside a flowing river.’’
