He who has fasted for Allah, the Glorious and Mighty, and is in the discomfort of heat and struck by thirst, will have his face wiped and be given the good news by a thousand angels whom Allah has entrusted to him until he breaks his fast; at that point Allah will say: “How sweet is your odor and your soul. Oh angels witness that I have forgiven him.”

(Imam Ja’far al Sadiq, as compiled in Leaves from a Sufi Journal)
