Narrated Sahl:
حَدَّثَنَا خَالِدُ بْنُ مَخْلَدٍ ، حَدَّثَنَا سُلَيْمَانُ بْنُ بِلاَلٍ ، قَالَ حَدَّثَنِي أَبُو حَازِمٍ ، عَنْ سَهْلٍ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " إِنَّ فِي الْجَنَّةِ بَابًا يُقَالُ لَهُ الرَّيَّانُ، يَدْخُلُ مِنْهُ الصَّائِمُونَ يَوْمَ الْقِيَامَةِ، لاَ يَدْخُلُ مِنْهُ أَحَدٌ غَيْرُهُمْ يُقَالُ أَيْنَ الصَّائِمُونَ فَيَقُومُونَ، لاَ يَدْخُلُ مِنْهُ أَحَدٌ غَيْرُهُمْ، فَإِذَا دَخَلُوا أُغْلِقَ، فَلَمْ يَدْخُلْ مِنْهُ أَحَدٌ " .
The Prophet (ﷺ) said, "There is a gate in Paradise called Ar-Raiyan, and those who observe fasts will enter through it on the Day of Resurrection and none except them will enter through it. It will be said, 'Where are those who used to observe fasts?' They will get up, and none except them will enter through it. After their entry the gate will be closed and nobody will enter through it."
