Musnad Ahmad 28:623

'Affan narrated to us, Abu 'Awanah narrated to us, Abu Bishr narrated to us, from Yusuf ibn Mahak, from 'Abdullah ibn 'Amr, who said: The Messenger of Allah (ﷺ) lagged behind us during a journey we were on. He caught up with us while the time for prayer, the 'Asr prayer, had already overtaken us. We were performing ablution and began wiping over our feet. He called out at the top of his voice, two or three times: "Woe to the heels from the Fire."
