Hadith 193

Narrated Jabir bin Samura (RA): Allah's Messenger (ﷺ) said: "Those people who raise their eyes to heaven while in Salat (prayer) should stop (doing so) or else their sight will not return to them." [Reported by Muslim]. Narrated 'Aishah (RA) in another narration of it from Muslim: I heard Allah's Messenger (ﷺ) said: "No Salat (prayer) can be (rightly offered) with food brought (before the worshiper) or when he is resisting the urge to relive himself of the two filths (i.e. urine and feces)."
