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.’”
