Prayer (Kitab Al-Salat): Prostration while reciting the Qur'an
(484)
Chapter: A Person On A Mount Hears A Verse Of Prostration, Or Someone Who Is Not Praying (Should He Prostrate?)
(6)
باب فِي الرَّجُلِ يَسْمَعُ السَّجْدَةَ وَهُوَ رَاكِبٌ وَفِي غَيْرِ الصَّلاَةِ
Sunan Abi Dawud 1413

Narrated Abdullah ibn Umar:

The Messenger of Allah (ﷺ) used to recite the Qur'an to us. When he came upon the verse containing prostration, he would utter the takbir (Allah is most great) and we would prostrate ourselves along with him.

The narrator 'Abd al-Razzaq said: Al-Thawri liked this tradition very much.

Abu Dawud said: This was liked by him for this contains the uttering of takbir.

حَدَّثَنَا أَحْمَدُ بْنُ الْفُرَاتِ أَبُو مَسْعُودٍ الرَّازِيُّ، أَخْبَرَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ عُمَرَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَقْرَأُ عَلَيْنَا الْقُرْآنَ فَإِذَا مَرَّ بِالسَّجْدَةِ كَبَّرَ وَسَجَدَ وَسَجَدْنَا ‏.‏ قَالَ عَبْدُ الرَّزَّاقِ وَكَانَ الثَّوْرِيُّ يُعْجِبُهُ هَذَا الْحَدِيثُ ‏.‏ قَالَ أَبُو دَاوُدَ يُعْجِبُهُ لأَنَّهُ كَبَّرَ ‏.‏
