Imam Baqir (a.s) said: “Two angels who were descending from the heavens to the Earth met each other. One asked the other about his mission. He said: “God gave me the mission to go to sea to force a fish to go to one of the oppressors so he, who had wished to catch it, would be able to do so. So I must go and force that fish in the sea towards him so that the oppressor can catch it, and achieve his last goal.” The other angel said: “My divine mission is even stranger than yours. God gave me the mission to go to a believer who is fasting and stays up at night to worship God, and is such a good worshipper that he is famous in the heavens. I am supposed to turn over the pan of food that he has just prepared for breaking his fast since God wants to test his faith this way.”
