Sayyiduna Nu’man bin Bashir (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings be upon him) delivering a sermon. He (peace be upon him) said:“I have warned you about the (Hell) Fire, I have cautioned you about the Fire, I have alerted you about the Fire.”He (peace be upon him) kept repeating this statement until, if all the people of the market had been present in my place, they would have heard it, and while saying this, his (peace be upon him) cloak fell at his feet.
