question #3 Sahih Muslim 1064c, Book 12, Hadith 190 : How did Khalid bin Walid, known as the Sword of Allah, respond to a situation involving a potential threat, and what was the Prophet’s instruction?

” There stood up ‘Umar b. Khattab (Allah be pleased with him), and said: Should I not strike his neck? Upon this he said: No. Then he turned away, and Khalid the Sword of Allah stood up against him, and said: Prophet of Allah. shall I not strike off his neck? He said, No, and then said: A people would rise from his progeny who would recite the Book of Allah glibly and fluently. ‘Umar said: I think he (the Holy Prophet) also said this: If I find them I would certainly kill them like Thamud.”
