Musnad Ahmad 132:11

Hassan narrated to us, Ibn Lahi'ah narrated to us, Zabban narrated to us, from Sahl ibn Mu'adh, from his father, from the Messenger of Allah, may Allah bless him and grant him peace, that he said: "Whoever suppresses his rage while he is able to take revenge, Allah, Blessed and Exalted is He, will call him before the heads of all creation, until He gives him the choice of the wide-eyed houris, to choose whichever of them he wishes. And whoever refrains from wearing fine clothing while he is able to do so, out of humility for Allah, Blessed and Exalted is He, Allah, Blessed and Exalted is He, will call him before the heads of all creation, until Allah, Exalted is He, gives him the choice of the garments of faith, to choose whichever of them he wishes."
