(9) باب وُجُوبِ غَسْلِ الرِّجْلَيْنِ بِكَمَالِهِمَا
'Abdullah b. Amr reported:
The Messenger of Allah (ﷺ) lagged behind us on a journey. We travelled (back) and be took him; and then came the time of the afternoon prayer, and as we were going to wipe our feet he (the Holy Prophet) called out: Woe to the heels because of Hell-fire.
