'Abdullah b. 'Amr reported: We returned from Mecca to Medina with the Messenger of Allah (ﷺ), and when we came to some water on the way, some of the people were in a hurry at the time of the afternoon prayer and performed ablution hurriedly; and when we reached them, their heels were dry, no water had touched them. The Prophet (ﷺ) said: Woe to (dry) heels, because of Hell-fire. Make your ablution thorough.
