Usama ibn Zayd said, “The Messenger of Allah, may Allah bless him and grant him peace, sent us to al-Huraqa, a sub-tribe of Juhayna, and we came upon the people in the morning at their springs. A man of the Ansar and I overtook one of their men. When we descended on him, he said, ‘There is no god but Allah.’ The Ansari held back from him, but I stabbed him with my spear until I had killed him. When we arrived in Madina, that reached the Prophet and he said, ‘O Usama, did you kill him after he had said, “There is no god but Allah”?’ I said, ‘Messenger of Allah, he was only trying to save himself.’ He said, ‘Did you kill him after he had said, “There is no god but Allah”?’ He continued to repeat it to me until I wished that I had not become Muslim until that day.” [Agreed upon]
