صَحِيحُ الْبُخَارِيِّ
Sahih al-Bukhari 3035, 3036
Fighting for the Cause of Allah (Jihaad)
Whosoever is unable to sit firm on a horse
حَدَّثَنِي مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا ابْنُ إِدْرِيسَ، عَنْ إِسْمَاعِيلَ، عَنْ قَيْسٍ، عَنْ جَرِيرٍ ـ رضى الله عنه ـ قَالَ مَا حَجَبَنِي النَّبِيُّ صلى الله عليه وسلم مُنْذُ أَسْلَمْتُ، وَلاَ رَآنِي إِلاَّ تَبَسَّمَ فِي وَجْهِي. وَلَقَدْ شَكَوْتُ إِلَيْهِ إِنِّي لاَ أَثْبُتُ عَلَى الْخَيْلِ. فَضَرَبَ بِيَدِهِ فِي صَدْرِي وَقَالَ اللَّهُمَّ ثَبِّتْهُ وَاجْعَلْهُ هَادِيًا مَهْدِيًّا .
Narrated Jarir: Allah's Messenger (ﷺ) did not screen himself from me since my embracing Islam, and whenever he saw me he would receive me with a smile. Once I told him that I could not sit firm on horses. He stroke me on the chest with his hand and said, "O Allah! Make him firm and make him a guiding and a rightly guided man."
