Reward of offering food to a believer in the way of Allah

1. My father رحمه الله said: it was narrated to me by Sa’d b. Abdillah from Ahmad b. Abi Abdillah from his father from Hamad b. Rib’i from Abi Abdillah عليه السلام who said: “One who feeds a believer for the sake of Allah will get the reward of feeding Fiyaam people.” The narrator asked, “What is meant by Fiyaam?” Imam عليه السلام replied, “A hundred thousand people.”
