Narrated Ibn `Umar:
حَدَّثَنَا أَبُو الْيَمَانِ ، أَخْبَرَنَا شُعَيْبٌ ، عَنِ الزُّهْرِيِّ ، قَالَ أَخْبَرَنِي سَالِمٌ ، أَنَّ ابْنَ عُمَرَ ـ رضى الله عنهما ـ قَالَ غَزَوْتُ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم قِبَلَ نَجْدٍ، فَوَازَيْنَا الْعَدُوَّ فَصَافَفْنَا لَهُمْ.
I took part in a Ghazwa towards Najd along with Allah's Messenger (ﷺ) and we clashed with the enemy, and we lined up for them.
