Musnad Ahmad 1700

It was narrated that "lyad bin Ghutaif said. We entered upon Abu "Ubaidah to visit him when he was sick. He said: I heard the Messenger of Allah (ﷺ) say: "Whoever spends wealth for the sake of Allah will be rewarded seven hundred fold, and whoever spends on himself and his family, or visits a sick person, or removes something harmful (from the road), his good deed will be rewarded tenfold. And fasting is a shield unless he makes a hole in it. If Allah tests a person with Physical sickness, it is a means of forgiveness for his sins.”
