Zirr bin Hubaysh (may Allah have mercy on him) narrates: I went early in the morning to Sayyiduna Safwan bin Assal al-Muradi (may Allah be pleased with him) to ask him about wiping over the leather socks, and he said: "The Prophet (peace and blessings be upon him) used to order us to wipe for three days and nights on a journey, and a day and a night for the resident." And I heard the Prophet (peace and blessings be upon him) say: "Whoever goes out early in the morning in search of knowledge, the angels spread their wings for him."
