حَدَّثَنَا مُحَمَّدُ بْنُ سِنَانٍ، حَدَّثَنَا فُلَيْحٌ، حَدَّثَنَا هِلاَلُ بْنُ عَلِيٍّ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " كُلُّ أُمَّتِي يَدْخُلُونَ الْجَنَّةَ، إِلاَّ مَنْ أَبَى ". قَالُوا يَا رَسُولَ اللَّهِ وَمَنْ يَأْبَى قَالَ " مَنْ أَطَاعَنِي دَخَلَ الْجَنَّةَ، وَمَنْ عَصَانِي فَقَدْ أَبَى ".Narrated Abu Huraira:Allah's Messenger (ﷺ) said, "All my followers will enter Paradise except those who refuse." They said, "O Allah's Messenger (ﷺ)! Who will refuse?" He said, "Whoever obeys me will enter Paradise, and whoever disobeys me is the one who refuses (to enter it)
