It is narrated on the authority of Usama b. Zaid that the Messenger of Allah (صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ) sent us in a raiding party. We raided Huraqat of Juhaina in the morning. I caught hold of a man and he said: There is no god but Allah, I attacked him with a spear. It once occurred to me and I talked about it to the Apostle (صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ). The Messenger of Allah (صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ) said: Did he profess" There is no god but Allah," and even then you killed him? I said: Messenger of Allah, he made a profession of it out of the fear of the weapon. He (the Holy Prophet (صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ)) observed: Did you tear his heart in order to find out whether it had professed or not? And he went on repeating it to me till I wished I had embraced Islam that day. Sa'd said: By Allah, I would never kill any Muslim so long as a person with a heavy belly, i. e., Usama, would not kill. Upon this a person remarked: Did Allah not say this: And fight them until there is no more mischief and religion is wholly for Allah? Sa'd said: We fought so that there should be no mischief, but you and your companions wish to fight so that there should be mischief.

It is narrated on the authority of Usama b. Zaid: The Messenger of Allah may peace be upon him) sent us to Huraqat, a tribe of Juhaina. We attacked that tribe early in the morning and defeated them and I and a man from the Ansar caught hold of a person (of the defeated tribe). When we overcame him, he said: There is no god but Allah. At that moment the Ansari spared him, but I attacked him with my spear and killed him. The news had already reached the Apostle (peace be upon him), so when we came back he (the Apostle (صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ)) said to me: Usama (RA), did you kill him after he had made the profession: There is no god but Allah? I said. Messenger of Allah, he did it only as a shelter. The Prophet (صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ) observed: Did you kill him after he had made the profession that there is no god but Allah? He (the Holy Prophet (صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ)) went on repeating this to me till I wished I had not embraced Islam before that day.
