Sayyiduna Uqbah bin Amir al-Juhani (may Allah be pleased with him) said: I set out from Syria for Madinah on a Friday and came to Umar bin al-Khattab (may Allah be pleased with him). He said to me: When did you put your leather socks on your feet? I said: On Friday. He said: Have you taken them off? I said: No. He said: You have acted in accordance with the Sunnah.
