Musnad Ahmad 30:1607

Yunus and Surayj narrated to us, they said: Fulayh narrated to us, from Hilal bin Ali, from Ata bin Yasar, from Abu Hurairah, that the Prophet, peace and blessings of Allah be upon him, said: "All of my nation will enter Paradise on the Day of Resurrection, except for those who refuse." They said: "And who would refuse, O Messenger of Allah?" He said: "Whoever obeys me will enter Paradise, and whoever disobeys me has refused."
