Compiled by Imam Abu Dawud as-Sijistani
حَدَّثَنَا أَحْمَدُ بْنُ صَالِحٍ، حَدَّثَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي عَمْرٌو، - يَعْنِي ابْنَ الْحَارِثِ - عَنِ ابْنِ أَبِي هِلاَلٍ، عَنْ عِيَاضِ بْنِ عَبْدِ اللَّهِ بْنِ سَعْدِ بْنِ أَبِي سَرْحٍ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، أَنَّهُ قَالَ قَرَأَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَهُوَ عَلَى الْمِنْبَرِ { ص } فَلَمَّا بَلَغَ السَّجْدَةَ نَزَلَ فَسَجَدَ وَسَجَدَ النَّاسُ مَعَهُ فَلَمَّا كَانَ يَوْمٌ آخَرُ قَرَأَهَا فَلَمَّا بَلَغَ السَّجْدَةَ تَشَزَّنَ النَّاسُ لِلسُّجُودِ فَقَالَ النَّبِيُّ صلى الله عليه وسلم " إِنَّمَا هِيَ تَوْبَةُ نَبِيٍّ وَلَكِنِّي رَأَيْتُكُمْ تَشَزَّنْتُمْ لِلسُّجُودِ " . فَنَزَلَ فَسَجَدَ وَسَجَدُوا .
The Messenger of Allah (ﷺ) recited surah Sad on the pulpit. When he reached the place of prostration (in the surah), he descended and prostrated himself and the people prostrated with him. When the next day came, he recited it. When he reached the place of prostration (in the surah), the people became ready for prostration. Thereupon the Messenger of Allah (ﷺ) said: This is the repentance of a Prophet ; but I saw you being ready for prostration. So he descended and prostrated himself and the people prostrated along with him.
