Mas-h [Touch] (Hadith No. 182)
Hadith no 181 is a repeat. Read it here.
Narrated Al-Mughira bin Shu’ba:
I was in the company of Allah’s Apostle on one of the journeys and he went out to answer the call of nature (and after he finished) I poured water and he performed ablution; he washed his face, forearms and passed his wet hand over his head and over the two Khuff, (leather socks).
Got your khuffs by now? (Ref: The Khuffs)
Anyhow, this Hadith gives us clear evidence of mas-h (touching/passing wet hands over one’s head and socks). The issue about the socks made of of leather/thread is debated. Mas-h is not contradicted in itself.
So go on doing mas-h in winter instead of washing your feet in every wudu! :)
