Arabic (Original)
أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُسَيَّبِ بْنِ إِسْحَاقَ قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ عُبَيْدِ بْنِ عَقِيلٍ قَالَ حَدَّثَنَا سَهْلُ بْنُ حَمَّادٍ قَالَ حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ عَنْ ثَابِتٍ عَنْ أَنَسٍ «اللَّهُمَّ لَا سَهْلَ إِلَّا مَا جَعَلْتَهُ سَهْلًا وَأَنْتَ تَجْعَلُ الْحَزْنَ سَهْلًا إِذَا شِئْتَ»
English Translation
Abu Hurairah (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings be upon him) said: 'When any of you stands for prayer, Satan comes and confuses him until he does not know how many rak'ahs he has prayed. If any of you experiences this, let him perform two prostrations while sitting.'
