Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ بَكْرٍ أَخْبَرَنَا ابْنُ جُرَيْجٍ أَخْبَرَنِي أَبُو الزُّبَيْرِ أَنَّهُ سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ وَذَكَرُوا الْأَنْصَارِيَّ يَقُولُ رَأَيْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهُوَ عَلَى رَاحِلَتِهِ يُصَلِّي النَّوَافِلَ فِي كُلِّ وَجْهٍ وَلَكِنَّهُ يَخْفِضُ السَّجْدَتَيْنِ مِنْ الرَّكْعَةِ وَيُومِئُ إِيمَاءً.
English Translation
Muhammad ibn Bakr informed us, Ibn Jurayj informed us, Abu al-Zubayr informed me that he heard Jabir ibn 'Abdullah — and they mentioned the Ansari man — say: I saw the Prophet, peace and blessings be upon him, while on his mount, praying voluntary prayers in every direction, but he would lower his head further for the two prostrations of each rak'ah than for the bowing, gesturing.
