The Prophet said: "There is a gate in Paradise called Ar-Raiyyan, those who fast shall be invited into it, and whoever was among those who fasted, then he will enter it; and whoever enters it, he will never thirst again."
عَنِ النَّبِيِّ ﷺ قَالَ إِنَّ فِي الْجَنَّةِ لَبَابًا يُدْعَى الرَّيَّانَ يُدْعَى لَهُ الصَّائِمُونَ فَمَنْ كَانَ مِنَ الصَّائِمِينَ دَخَلَهُ وَمَنْ دَخَلَهُ لَمْ يَظْمَأْ أَبَدًا
