Sahl ibn Sa’id reported: The Messenger of Allah, peace be upon him, said, “Indeed, there is a gate in Paradise called Ar-Rayyan which only those who fasted will enter on the Day of Resurrection. No one else will enter it along with them. It will be said: Where are those who used to fast so that they may enter? When the last of them enter, it will be closed and no one else will enter through it.”
[Sahih Muslim, Book 6, Number 2569]
عَنْ سَهْلِ بْنِ سَعْدٍ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ
إِنَّ فِي الْجَنَّةِ بَابًا يُقَالُ لَهُ الرَّيَّانُ يَدْخُلُ مِنْهُ
الصَّائِمُونَ يَوْمَ الْقِيَامَةِ لَا يَدْخُلُ مَعَهُمْ أَحَدٌ
غَيْرُهُمْ يُقَالُ أَيْنَ الصَّائِمُونَ فَيَدْخُلُونَ مِنْهُ فَإِذَا
دَخَلَ آخِرُهُمْ أُغْلِقَ فَلَمْ يَدْخُلْ مِنْهُ أَحَدٌ
