It is narrated from Sayyiduna Khabbab (may Allah be pleased with him) that he said: "I came to the Messenger of Allah (peace and blessings be upon him) while he (peace and blessings be upon him) was lying in the shade of a tree with his hand placed under his head. I said: O Messenger of Allah! Will you not supplicate to Allah against these people who, we fear, will turn us away from our religion? He (peace and blessings be upon him) turned his blessed face away from me. I moved round in front of him again, and he (peace and blessings be upon him) turned his face away again. This happened three times; each time I said this to him (peace and blessings be upon him), and he (peace and blessings be upon him) turned his radiant face away. The third time he (peace and blessings be upon him) sat up and said: O people! Fear Allah. By Allah! A man among the believers before you would have a saw placed on his head and be split into two pieces, yet he would not turn away from his religion. Fear Allah, for Allah, the Mighty and Majestic, is going to grant you victory and set (your affairs) right."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Mughirah except Salamah (may Allah have mercy on him); no one narrated it from Salamah except his two sons, Muhammad and Yahya (may Allah have mercy on them both); and no one narrated it from Muhammad bin Salamah except Hassan (may Allah have mercy on him)."
