Arabic (Original)
حَدَّثَنَا خَلَفُ بْنُ الْوَلِيدِ حَدَّثَنَا خَالِدٌ عَنْ سَعِيدٍ الْجُرَيْرِيِّ عَنِ السَّعْدِيِّ عَنْ أَبِيهِ أَوْ عَمِّهِ قَالَ رَمَقْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي صَلَاتِهِ فَكَانَ يَمْكُثُ فِي رُكُوعِهِ وَسُجُودِهِ قَدْرَ مَا يَقُولُ سُبْحَانَ اللَّهِ وَبِحَمْدِهِ ثَلَاثًا.
English Translation
Khalaf ibn al-Walid narrated to us: Khalid narrated to us, from Sa'id al-Jurayri, from al-Sa'di, from his father or his uncle, who said: I closely observed the Messenger of Allah (peace and blessings be upon him) in his prayer, and he would remain in his bowing and his prostration for about the time it takes to say "Glory be to Allah, and praise be to Him" three times.
