It is narrated from Sayyiduna Mu'adh bin Anas al-Juhani (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever gives up (fine) clothing out of humility for Allah, the Mighty and Majestic, while being able to afford it, Allah Almighty will call him on the Day of Resurrection before all of creation, until He gives him the choice among the garments of faith to wear whichever of them he wishes."
