Al-Adab Al-Mufrad #1082

Mu'awiya ibn Hudayj said, "I came to 'Umar ibn al-Khattab, may Allah be pleased with him, and asked him for permission to enter. They told me, 'Stay where you are until he comes to you.' I sat down near his door." He continued, "'Umar came out to me, called for water and did wudu'. Then he wiped over his leather socks. I said, 'O Amir al'-Mu'minin, is this on account of urine?' He replied, 'On account of urine or other things.'"
