He urinated, then performed ablution and wiped over his leather socks. Someone said to him, "You do this?"He replied, "Yes. I saw the Messenger of Allah ﷺ urinate, then perform ablution and wipe over his leather socks."
أنه بال، ثم توضأ ومسح على خفيه، فقيل له: تفعل هذا؟ فقال: نعم؛ رأيت رسول الله ﷺ بال ثم توضأ ومسح على خفيه.
Bukhari narrated it in the Book of Prayer (387) and Muslim in the Book of Purification (272), and this is his wording, both from Amash, from Ibrahim, from Hammam bin Harith, who said, "I saw Jareer urinate," and he mentioned it.Amash said, Ibrahim said, "This hadith pleased them, because Jareer's conversion to Islam came after the revelation of Maidah."In a narration recorded by Tirmidhi, Jareer was asked, "When did you become Muslim?" He said, "After Maidah."
