عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: سَأَلْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ عَنِ التَّلَفُّتِ فِي الصَّلَاةِ فَقَالَ: ((اخْتِلَاسٌ يَخْتَلِسُهُ الشَّيْطَانُ مِنْ صَلَاةِ الْعَبْدِ))
Sayyidah Aisha (may Allah be pleased with her) says: I asked the Noble Prophet (peace and blessings be upon him) about glancing around during prayer, so he said: This is snatching, which Satan snatches from a servant’s prayer.
