Benefits of the Hadith: (… then the Messenger of Allah (peace and blessings be upon him) slept until he snored, and whenever he slept, he would snore. Then the mu'adhdhin came to him, and he went out and prayed.)

The Shaykh : This hadith contains, in addition to what has been mentioned previously, the benefit that sleep does not invalidate the wudu', because the Prophet (peace and blessings be upon him and his family) slept until he snored. Many scholars have cited this as evidence for the view that sleep is not an absolute invalidator. However, the correct view is that sleep is an invalidator of wudu', based on the hadith of Safwan ibn 'Uasal, who mentioned wiping over the leather socks, but stated that if one urinates, defecates, or sleeps, the wudu' is invalidated. What is reported from the Prophet (peace and blessings be upon him and his family) regarding his sleep not invalidating wudu' is to be understood as one of his specific characteristics, for he (peace and blessings be upon him) would sleep with his eyes but not with his heart. His internal awareness remained present, whereas his external state was not. For this reason, he missed the Fajr prayer and did not wake up for the dawn, as mentioned in the hadith of Abu Qatadah and others. Similarly, here he slept until he snored. Therefore, the conclusion is that sleep invalidates wudu', but is it an invalidator in itself and a state of ritual impurity in itself, or is it a place where ritual impurity is likely to occur?
The student: The second.

The Shaykh : The correct view is the second one: that it is a place where ritual impurity is likely to occur. If a person is convinced that if he had become ritually impure, he would have felt it, then his wudu' is not invalidated. Anas said: The Companions of the Prophet (peace and blessings be upon him) would wait for the 'Isha' prayer until their heads would nod, and then they would pray without performing wudu'. Yes, has the time for the question come?
The reader: No, Shaykh.
