It is narrated from Sayyiduna Mughirah bin Shu’bah (may Allah be pleased with him), he says: I performed ablution for the Noble Prophet (peace and blessings be upon him) during a journey. The Prophet (peace and blessings be upon him) washed his face and arms, then wiped his head and also wiped over his socks. I said: O Messenger of Allah! Should I not remove your socks? The Prophet (peace and blessings be upon him) said: No, when I put them on my feet were clean, and since then I have not walked barefoot. Then the Prophet (peace and blessings be upon him) performed the Fajr prayer.
