Abu Abd al-Rahman narrated to us, Sa'id narrated to us, he said: Abu Marhum Abd al-Rahim ibn Maymun narrated to me, from Sahl ibn Mu'adh ibn Anas al-Juhani, from his father, who said: The Messenger of Allah, peace and blessings of Allah be upon him, said: "Whoever abandons clothing while he is able to afford it, 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 on the Day of Resurrection, so that He may let him choose whichever of the garments of faith he wishes."
