Riyad as-Salihin, Book 4, Hadith 802 (In-Book) ⓘ

Mu`adh bin Anas (May Allah be pleased with him) reported: Messenger of Allah said, "Whoever gives up wearing elegant and expensive garments out of humbleness, when he can do so, Allah will call him on the Day of Resurrection and before all the creations, He will give him the choice to wear whichever garment of Iman he would like to wear." [At-Tirmidhi].

وعن معاذ بن أنس رضى الله عنه أن رسول الله صلى الله عليه وسلم قال‏:‏ ‏ "‏ من ترك اللباس تواضعاً لله، وهو يقدر عليه، دعاه الله يوم القيامة على رؤوس الخلائق حتى يخيره من أي حلل الإيمان شاء يلبسها‏" ‏.‏
