Mu'jam Kabir Tabarani 1710 — I was with the Messenger of Allah ﷺ when

Sayyiduna Jundub bin Sufyan (may Allah be pleased with him), a man from the tribe of Bajilah, said: I was with the Messenger of Allah (peace and blessings be upon him) when a bearer of good news came to him (peace and blessings be upon him) from his detachment and informed him (peace and blessings be upon him) of the victory that Allah had granted his detachment and of the conquest that Allah had given them. He said: O Messenger of Allah, while we were pursuing the enemy, and Allah Almighty had routed them, I caught up with a man with my sword. When he sensed that the sword was about to strike him, he was running and saying: I am a Muslim, I am a Muslim. He (peace and blessings be upon him) said: "And you killed him?" He said: O Messenger of Allah, he was only seeking refuge. He (peace and blessings be upon him) said: "Why did you not split open his heart and see whether he was truthful or lying?" He said: Even if I had split open his heart, what would I have known? His heart is nothing but a piece of flesh! He (peace and blessings be upon him) said: "You neither knew what was in his heart, nor did you believe his tongue." He said: O Messenger of Allah, ask forgiveness for me. He (peace and blessings be upon him) said: "I will not ask forgiveness for you." Then that man died and the people buried him, and in the morning he was found lying on the surface of the ground. Then they buried him again, and again in the morning he was found on the surface of the ground; this happened three times. When they saw this, they felt ashamed and disgraced by what had befallen him, so they carried him and threw him into one of the mountain ravines.
