Section 1
وَعَنْ سَهْلِ بْنِ سَعْدٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: فِي الْجَنَّةِ ثَمَانِيَةُ أَبْوَابٍ مِنْهَا: بَابٌ يُسَمَّى الرَّيَّانَ لَا يدْخلهُ إِلَّا الصائمون
Sahl b. Sa'd reported God’s messenger as saying, "In paradise there are eight gates among which is a gate called ar-Rayyan which only those who fast will enter." (Bukhari and Muslim.)
