Sayyiduna Abu Hurayrah (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "There were presented to me the first three who will enter Paradise and the first three who will enter Hell. As for the first three to enter Paradise: the martyr; a slave who fulfilled the rights of Allah and was sincere to his master; and a poor man with dependants who refrained from begging. As for the first three to enter Hell: a ruler imposed on the people by force; a wealthy man who did not give the due of his wealth (zakah); and a sinful poor man."
