It is narrated from Sayyiduna Khubaib bin Yasaf (may Allah be pleased with him), he says: I and a man from my tribe came to the Messenger of Allah (peace and blessings be upon him), while he (peace and blessings be upon him) was about to go for a battle. We had not yet become Muslims. So we said: Indeed, we feel ashamed that our tribe participates in a battle and we are not included with them. The Messenger of Allah (peace and blessings be upon him) said: Have you become Muslims? They said: No. The Messenger of Allah (peace and blessings be upon him) said: Indeed, in opposition to the polytheists, we do not seek help from the polytheists. Upon hearing this statement, we became Muslims and participated in that battle with the Messenger of Allah (peace and blessings be upon him). I killed a man and he had also struck me a blow. Then I married his daughter. She used to say: Do not lose the man who struck you between the shoulder and the side, and I used to say to her: Do not lose the man who quickly sent your father into the fire.
