Riyad as-Salihin, Book 4, Hadith 791 (In-Book) ⓘ

Ibn 'Umar (May Allah be pleased with him) reported: The Prophet said, "Whoever allows his lower garment to drag out of vanity will find that Allah will not look at him on the Day of Resurrection." On this Abu Bakr (May Allah be pleased with him) submitted: "O Messenger of Allah! My lower garment keeps sliding down though I take care to pull it and wrap it." Messenger of Allah said, "You are not of those who do it out of vanity."[Al- Bukhari].

وعن ابن عمر رضى الله عنهما أن النبي صلى الله عليه وسلم قال‏:‏ ‏"‏من جر ثوبه خيلاء لم ينظر الله إليه يوم القيامة‏"‏ فقال أبو بكر‏:‏ يا رسول الله إن إزاري يسترخي إلى أن أتعاهده، فقال له رسول الله صلى الله عليه وسلم‏:‏ ‏"‏إنك لست ممن يفعله خيلاء‏"‏‏.‏ ‏‏.‏
