Abdullah b. 'Amr reported:
We returned from Mecca to Medina with the Messenger of Allah ( صلی اللہ علیہ وسلم ), 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 ( صلی اللہ علیہ وسلم ) said: Woe to (dry) heels, because of Hell-fire. Make your ablution thorough.
