(2) باب مَنْ جَرَّ إِزَارَهُ مِنْ غَيْرِ خُيَلاَءَ
Narrated `Abdullah bin `Umar:
The Prophet (ﷺ) said Allah will not look, on the Day of Resurrection at the person who drags his garment (behind him) out of conceit. On that Abu Bakr said, "O Allah's Messenger (ﷺ)! One side of my Izar hangs low if I do not take care of it." The Prophet (ﷺ) said, 'You are not one of those who do that out of conceit."
