Prayer
Prostration while Reciting the Qur’an - Section 2
وَعَنِ ابْنِ عُمَرَ: أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ سَجَدَ فِي صَلَاةِ الظُّهْرِ ثُمَّ قَامَ فَرَكَعَ فَرَأَوْا أَنَّهُ قَرَأَ تَنْزِيلَ السَّجْدَةَ. رَوَاهُ أَبُو دَاوُد
Ibn ‘Umar said that the Prophet (ﷺ) made a prostration in the noon prayer, then stood up and bowed; and they thought he recite Tanzil, i.e. sura as-Sajda (Al-Qur’an; 32). Abu Dawud transmitted it.
