Useful information: Wiping the Feet During Ablution ( Wudu' )
The followers of the ahl al-bayt ( pbut ) follow what the Holy Qur'an teaches them to do during wudu' by wiping their feet instead of washing them since the Holy Qur'an commands: "O you who believe! When you intend your prayers, wash your faces and your hands from the elbows and wipe (by passing wet hands over) your head and your feet up to the ankles."Qur'an 5:6
Those who practice the washing of their feet during wudu' argue that "your feet" in the Holy Qur'an is linked to washing the face, whereas the followers of the ahl al-bayt argue that "your feet" is linked to rubbing the head and, therefore, they should be wiped but not washed. In support of the latter view, Ibn 'Abbas narrates from the Holy Prophet ( pbuh&hf ) that they used to rub their feet during the time of the Holy Prophet ( pbuh&hf ). Wudhu' al-Nabi , al-Shahrastani
