Narrated Jarir:

Allah's Apostle 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."

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 ﷺ 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 ".
