Hadith 31:20
Abu al-Ahwas narrated to us, from Simak, from al-Nu’man ibn Bashir, who said: I heard the Messenger of Allah (ﷺ) while he was on the pulpit saying: "I warn you of the Fire," until one of the sides of his cloak fell from his shoulders. And he was saying: "I warn you of the Fire," until, had he been in this place of mine, the people of the market—or whoever Allah willed among them—would have heard him.
حدثنا أبو الأحوص عن سماك عن النعمان بن بشير قال سمعت رسول الله صلى الله عليه وسلم وهو على المنبر يقول أنذركم النار حتى سقط إحدى عطفي ردائه عن منكبيه وهو يقول أنذركم النار حتى لو كان في مكاني هذا لأسمع أهل السوق أو من شاء الله منهم
