عَن عُقْبَةَ بْنِ عَامِرٍ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهُوَ عَلَى الْمِنْبَرِ يَقُول: " (وَأَعدُّوا لَهُ مَا استطَعْتُمْ منْ قُوَّةٍ) أَلَا إِنَّ الْقُوَّةَ الرَّمْيُ أَلَا إِنَّ الْقُوَّةَ الرَّمْيُ أَلَا إِنَّ الْقُوَّةَ الرَّمْيُ) رَوَاهُ مُسْلِمٌ

Jarir b. ‘Abdallah told that he saw God’s Messenger twisting his finger in a horse’s forelock and saying, "The horses have good tied in their forelocks till the day of resurrection, i.e. reward and spoil.” Muslim transmitted it.
