Chapter : It to forbidden to trail one's garment out of conceit or pride.
Mubammad b. 'Abbad b. ja'far reported: I ordered Muslim b. Yasar, the freed slave of Nafi' b. 'Abd al-Harith, while I was sitting between them, that he should ask Ibn 'Umar if he had heard anything from Allah's Messenger (may peace be upon him) pertaining to one who trails his lower garment out of pride. He said: I heard him (the Holy Prophet) as saying: Allah will not look toward him on the Day of Resurrection.
