The Messenger of Allah ﷺ fell behind us during a journey we were making. He caught up with us when we were rushing to perform the afternoon prayer, and we were making wudu, wiping over our feet. He called out at the top of his voice, "Woe to the heels from the Fire," repeating it two or three times.
حدثنا مسدد قال حدثنا أبو عوانة عن أبي بشر عن يوسف بن ماهك
