Riyad as-Salihin

Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah (ﷺ) said, "Everyone of my Ummah will enter Jannah except those who refuse". He was asked: "Who will refuse?" He (ﷺ) said, "Whoever obeys me, shall enter Jannah, and whosoever disobeys me, refuses to (enter Jannah)".
