as we know it. As for waking from night sleep, there is a difference of opinion regarding its obligation. It is narrated from Ahmad that it is obligatory, which is the evident view from him and the chosen view of Abu Bakr; it is also the position of Ibn ‘Umar, Abu Hurayrah, and al-Hasan al-Basri, based on the statement of the Prophet (peace and blessings of Allah be upon him): "If one of you wakes from his sleep, he should wash his hands three times before inserting them into the vessel, for one of you does not know where his hand spent the night." Agreed upon (36). In a version by Muslim: "He should not submerge his hand into the water for wudu until he has washed it three times." His command implies obligation, and his prohibition implies prohibition. It is also narrated that this is recommended and not obligatory. This is the opinion of ‘Ata’, Malik, al-Awza‘i, al-Shafi‘i, Ishaq, the Ashaab al-Ra’y, and Ibn al-Mundhir, because Allah the Almighty said: {O you who have believed, when you rise to prayer, wash your faces} (37), to the end of the verse. Zayd ibn Aslam (38) said in his exegesis: "When you rise from night sleep" (39).

Moreover, since he is rising from sleep, he is analogous to one rising from daytime sleep. The hadith is to be interpreted as recommendation, due to the justification for it provided in the text, which is his saying: "For he does not know where his hand spent the night." The occurrence of doubt over the certainty of purity does not affect it, just as if one were certain of purity and doubted the occurrence of hadath (ritual impurity); this indicates that he intended recommendation.
Section: There is no difference of opinion that it is not obligatory to wash them after daytime sleep. Al-Hasan equated night sleep and daytime sleep regarding the obligation, due to the generality of his saying: "If one of you wakes from his sleep."
As for us, there is in the report what indicates the intended meaning is night sleep, due to his saying: "For he does not know where his hand spent the"
