(If one of you wakes up from sleep, he should not dip his hand in the vessel, for he does not know where his hand spent the night) includes sleep at night and sleep during the day?

The Shaykh : ... And regarding the hadith, do we say that the statement of the Messenger (peace and blessings be upon him) includes sleep at night and sleep during the day, and that his statement is based on the predominant case, which is sleep at night, and that the ruling is taken as general because the cause is more specific than the ruling, so the generality is adopted? Just as in a specific school of thought, they say that the right of pre-emption is not obligatory except in land. Do you know the right of pre-emption or not? The right of pre-emption: if your partner in a piece of land sells it, you have the right to take it from the buyer. He says, "The right of pre-emption is not obligatory except in land," based on his statement, "When rights are established and paths are diverted, there is no pre-emption," even though the beginning of the hadith states that the Prophet (peace and blessings be upon him) ruled with the right of pre-emption in everything that had not been ruled upon. So they specify the generality by the cause or by the ruling in some of the opinions. We say that the apparent view is that a person should not dip his hand in the vessel when he wakes up from sleep, whether it is at night or during the day. This is the most common and the best. And Allah knows best.
