The Messenger of Allah ﷺ said, "I warn you of the Fire! I warn you of the Fire!" He said it with such force that even a man at the farthest end of the marketplace would have heard him, and the people of the marketplace heard his voice while he was on the pulpit.In another narration, he cried out so vigorously that the cloak on his shoulder fell to his feet.
قال رسول الله ﷺ: أنذرتكم النار! أنذرتكم النار! حتى لو كان رجل في أقصى السوق سمعه، وسمع أهل السوق صوته وهو على المنبر. وفي رواية: حتى وقعت خميصة كانت على عاتقه عند رجله.
Reported by Ahmad (18360, 18398, 1899), Ibn Hibban (644, 667), and Hakim (1/287), all of them via Shubah, from Simak, who said, "I heard Numan bin Bashir," and then he related it.Its chain is hasan, because of Simak bin Harb, whose narrations are hasan except when he narrates from Ikrima, and this narration is not from him. Hakim said, "Sahih according to the criterion of Muslim, though the two of them did not include it."
