Explanation

This Hadīth mentions that there were men who would collapse while standing in prayer out of hunger and weakness. These belonged to the people of the Suffah, i.e. the ascetic Companions who were destitute and homeless. They were more or less seventy men who lived at the back of the Prophet’s Mosque as they had no homes, no money, and no children. The desert people would think that they were insane when they saw them collapsing in prayer. So the Prophet (may Allah's peace and blessings be upon him) said to the people of the Suffah: "If you knew what was in store for you with Allah of good things, you would love to be in more poverty and need."
