It is narrated from Umair bin Hani (may Allah have mercy on him) that a man was teaching another man the Qur'an, then that man went for Hajj and gave a bow as a gift to the one who had taught him. He went to Sayyiduna Awf bin Malik (may Allah be pleased with him) and informed him, so he said: Return it. He said: I want to use it for jihad. Sayyiduna Awf (may Allah be pleased with him) said: Return it. He said: I want to use it for jihad. Sayyiduna Awf (may Allah be pleased with him) said: Do you want to hang the bow of Hellfire around your neck? So that man returned the bow to its owner.
