Sayyiduna Usamah (may Allah be pleased with him) said: the Messenger of Allah (peace and blessings be upon him) said: "I stood at the gate of Paradise and saw that most of those who entered it were the poor, and I saw that the wealthy were held back, except those who were people of the Fire, for they had already been ordered to be taken to the Fire."
