Yahya related to me from Malik from Ibn Shihab from Abu Salama ibn Abdar-Rahman ibn Awf from Abu Hurayra that the Messenger of Allah, (ﷺ), said, "When you stand in prayer, Shaytan comes to you and confuses you until you do not know how much you have prayed. If you find that happening do two sajdas from the sitting position."
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ
Yahya related to me from Malik that he had heard that the Messenger of Allah, (ﷺ), said, "I forget or I am made to forget so that I may establish the sunna."
وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ
Yahya related to me from Malik that he had heard that a man questioned al-Qasim ibn Muhammad saying, "My imagination works in the prayer, and it happens to me a lot." Al-Qasim ibn Muhammad said, "Go on with your prayer, for it will not go away from you until you go away saying, 'I have not completed my prayer.' "
