عَنْ سَهْلٍ رضى اللّٰہ عنه عَنِ النَّبِيِّ صلّى اللّٰہ عليه وسلّم 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.
Hazrat Sahlra narrated:
“The Prophetsa said, ‘In Paradise there is a gate called ar-Rayyan. On the Day of Resurrection, those who used to fast will enter through it and none besides them will enter through it. It will be announced, ‘Where are those who used to fast?’ and they will rise and none besides them will enter through it. Then when they have entered, it will be closed and no one will enter through it.’”
(Sahih al-Bukhari, Kitab as-sawm, Bab ar-rayyanu li s-sa’imin, Hadith 1896)
