Musnad Ahmad 30:2365

Isma'il ibn Ibrahim narrated to us, he said: Hisham al-Dastawa'i narrated to us, from Yahya ibn Abi Kathir, from 'Amir al-'Uqayli, from his father, from Abu Hurayrah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "The first three who will enter Paradise and the first three who will enter the Fire were presented to me. As for the first three who will enter Paradise: they are the martyr, a slave who worshipped his Lord well and was sincere to his master, and a chaste person who abstains from what is forbidden and has a family to support. And as for the first three who will enter the Fire: they are an oppressive ruler, a possessor of wealth who does not give the right of his wealth, and a boastful poor person."
