Suwaid b. Wahb quoted a son of a Companion of God’s messenger who said his father reported God’s messenger as saying, “He who gives up wearing beautiful garments when he is able to do so (out of humility, as is stated in a version) will be clothed by God with the robe of honour, and he who marries for God's sake will be crowned by God with the crown of the kingdom.”
Abu Dawud transmitted it, and Tirmidhi transmitted the tradition about the clothing on Suwaid’s authority on the authority of Mu'adh b. Anas.
Ibn ‘Umar reported God’s messenger as saying, “He who wears grand clothes in this world will be made by God to wear humble clothes on the day of resurrection.”
Ahmad, Abu Dawud and Ibn Majah transmitted it.
‘ Amr b. Shu'aib, on his father’s authority, told that his grandfather reported God’s messenger as saying, “God likes the mark of His favour to be seen on his servant.” (People whom God has prospered should wear clothes suitable for their station, for the poor may recognise them as people able to give charity. The learned should not conceal their learning, so that others may benefit from it)
Tirmidhi transmitted it.
