42. Ibn 'Umar (radhiAllaahu 'anhumaa) said: Rasoolullah (sallallaahu 'alaihi wa

sallam) fell behind us and then came upon us during a journey, then we found him and it was time for 'Asr - so we began to make wudoo and wipe over our feet, so he (sallallaahu 'alaihi wa sallam) called out at the top of his voice Woe to the ankles from the Fire. (two or three times) [Al-Bukhaaree (al Fath, 1/232) and Muslim, 3/128]. Al-Nawawi says in his explanation of Sahih Muslim after mentioning the hadith: Muslim's intention (rahimahullah) in quoting these hadith was to prove with it the obligation of washing the feet - and that wiping them is not sufficient.
