(Imām Bukhārī narrates): Musaddad narrated to us, he said: Abū al-Ahwas narrated to us, he said: Ash'ath ibn Sulaim narrated to us, from his father, from Masrūq, from 'Ā'ishah, may Allāh be pleased with her, she narrates:
I asked the Messenger of Allāh ﷺ about turning around in prayer. He said: This is a snatching that Satan makes of a part of the servant's prayer.
حَدَّثَنَا مُسَدَّدٌ، قَالَ حَدَّثَنَا أَبُو الأَحْوَصِ، قَالَ حَدَّثَنَا أَشْعَثُ بْنُ سُلَيْمٍ، عَنْ أَبِيهِ، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ، قَالَتْ سَأَلْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم عَنْ الاِلْتِفَاتِ فِي الصَّلاَةِ فَقَالَ " هُوَ اخْتِلاَسٌ يَخْتَلِسُهُ الشَّيْطَانُ مِنْ صَلاَةِ الْعَبْدِ ".
