Sunan Ibn Majah Book 24, Hadith 2810

حَدَّثَنَا مُحَمَّدُ بْنُ إِسْمَاعِيلَ بْنِ سَمُرَةَ، أَنْبَأَنَا عُبَيْدُ اللَّهِ بْنُ مُوسَى، عَنْ أَشْعَثَ بْنِ سَعِيدٍ، عَنْ عَبْدِ اللَّهِ بْنِ بُسْرٍ، عَنْ أَبِي رَاشِدٍ، عَنْ عَلِيٍّ، قَالَ كَانَتْ بِيَدِ رَسُولِ اللَّهِ صلى الله عليه وسلم قَوْسٌ عَرَبِيَّةٌ فَرَأَى رَجُلاً بِيَدِهِ قَوْسٌ فَارِسِيَّةٌ فَقَالَ ‏ "‏ مَا هَذِهِ أَلْقِهَا وَعَلَيْكُمْ بِهَذِهِ وَأَشْبَاهِهَا وَرِمَاحِ الْقَنَا فَإِنَّهُمَا يَزِيدُ اللَّهُ بِهِمَا فِي الدِّينِ وَيُمَكِّنُ لَكُمْ فِي الْبِلاَدِ ‏"‏ ‏.‏

It was narrated that ‘Ali said:“The Messenger of Allah (ﷺ) had an Arabian bow in his hand, and he saw a man who had a Persian bow in his hand. He said: ‘What is this? Throw it away. You should use this and others like it, and Qana* spears. Perhaps Allah will support His religion thereby and enable you to conquer lands.’”
