It has been narrated on the authority of Ibn Amir who said:
حَدَّثَنَا هَارُونُ بْنُ مَعْرُوفٍ ، أَخْبَرَنَا ابْنُ وَهْبٍ ، أَخْبَرَنِي عَمْرُو بْنُ الْحَارِثِ ، عَنْ أَبِي عَلِيٍّ، ثُمَامَةَ بْنِ شُفَ ىٍّ أَنَّهُ سَمِعَ عُقْبَةَ بْنَ عَامِرٍ ، يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم وَهُوَ عَلَى الْمِنْبَرِ يَقُولُ " وَأَعِدُّوا لَهُمْ مَا اسْتَطَعْتُمْ مِنْ قُوَّةٍ أَلاَ إِنَّ الْقُوَّةَ الرَّمْىُ أَلاَ إِنَّ الْقُوَّةَ الرَّمْىُ أَلاَ إِنَّ الْقُوَّةَ الرَّمْىُ "
I heard the Messenger of Allah (ﷺ) say-and he was delivering a sermon from the pulpit: Prepare to meet them with as much strength as you can afford. Beware, strength consists in archery. Beware, strength consists in archery. Beware, strength consists in archery.
