Narrated Jabir ibn Abdullah: We proceeded in the company of the Messenger of Allah (ﷺ) for the battle of Dhat ar-Riqa. One of the Muslims killed the wife of one of the unbelievers. He (the husband of the woman killed) took an oath saying: I shall not rest until I kill one of the companions of Muhammad. He went out following the footsteps of the Prophet (ﷺ). The Prophet (ﷺ) encamped at a certain place. He said: Who will keep a watch on us? A person from the Muhajirun (Emigrants) and another from the Ansar (Helpers) responded. He said: Go to the mouth of the mountain-pass. When they went to the mouth of the mountain-pass the man from the Muhajirun lay down while the man from the Ansar stood praying. The man (enemy) came to them. When he saw the person he realised that he was the watchman of the Muslims. He shot him with an arrow and hit the target. But he (took the arrow out and) threw it away. He (the enemy) then shot three arrows. Then he (the Muslim) bowed and prostrated and awoke his companion. When he (the enemy) perceived that they (the Muslims) had become aware of his presence, he ran away. When the man from the Muhajirun saw the (man from the Ansar) bleeding, he asked him: Glory be to Allah! Why did you not wake me up the first time when he shot at you. He replied: I was busy reciting a chapter of the Qur'an. I did not like to leave it.
