Sahih Muslim , Book 31, Hadith 6051 (USC-MSA) ⓘ

Jarir reported: Since I embraced Islam Allah's Messenger never refused to see me and he did not see me but with a smile on his face. Ibn Numair has made this addition to this hadith which has been reported on the authority of Ibn Idris that he (Jarir) made this complaint to him (to the Holy Prophet): I cannot sit upon the horse with firmness, whereupon he (Allah's Apostle) struck his chest with his hand and prayed: O Allah, make him steadfast and rightly-guided.

وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا وَكِيعٌ، وَأَبُو أُسَامَةَ عَنْ إِسْمَاعِيلَ، ح وَحَدَّثَنَا ابْنُ نُمَيْرٍ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ إِدْرِيسَ، حَدَّثَنَا إِسْمَاعِيلُ، عَنْ قَيْسٍ، عَنْ جَرِيرٍ، قَالَ مَا حَجَبَنِي رَسُولُ اللَّهِ صلى الله عليه وسلم مُنْذُ أَسْلَمْتُ وَلاَ رَآنِي إِلاَّ تَبَسَّمَ فِي وَجْهِي ‏.‏ زَادَ ابْنُ نُمَيْرٍ فِي حَدِيثِهِ عَنِ ابْنِ إِدْرِيسَ وَلَقَدْ شَكَوْتُ إِلَيْهِ أَنِّي لاَ أَثْبُتُ عَلَى الْخَيْلِ فَضَرَبَ بِيَدِهِ فِي صَدْرِي وَقَالَ ‏ "‏ اللَّهُمَّ ثَبِّتْهُ وَاجْعَلْهُ هَادِيًا مَهْدِيًّا ‏" ‏ ‏.‏
