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)".[Al- Bukhari].
