The Book of Prayer
Bulugh al-Maram 243
Narrated 'Aishah (RA):
I asked Allah's Messenger (ﷺ) about looking around during prayer and he said, "It is something which the devil snatches from a person's prayer." [Reported by al-Bukhari].
عَنْ عَائِشَةَ ‏-‏-رَضِيَ اَللَّهُ عَنْهَا‏-‏- قَالَتْ : { سَأَلْتُ رَسُولَ اَللَّهِ ‏- صلى الله عليه وسلم ‏-عَنْ اَلِالْتِفَاتِ فِي اَلصَّلَاةِ ? فَقَالَ : "هُوَ اِخْتِلَاسٌ يَخْتَلِسُهُ اَلشَّيْطَانُ مِنْ صَلَاةِ اَلْعَبْدِ } رَوَاهُ اَلْبُخَارِيُّ .‏ 1
