120. Chapter: On the recommendation to avoid fine clothing out of humility
802. Mu'adh ibn Anas reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "If anyone gives up fine clothing, which he could wear, out of humility in front of Allah , Allah will summon him on the Day of Rising in front of all other creatures to give him the choice of whatever robes of belief he wishes to wear." [at-Tirmidhi]
