al-Rayyan: the entrance gate of Jannah exclusively for those who fast

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."  

عَنِ النَّبِيِّ ﷺ 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۔»  

Messenger of Allah ﷺ said, "Whoever gives two kinds (of things or property) in charity for Allah's Cause, will be called from the gates of Paradise and will be addressed, 'O slaves of Allah! Here is prosperity.' So, (1) whoever was amongst the people who used to offer their prayers, will be called from the gate of the prayer; and (2) whoever was amongst the people who used to participate in Jihad, will be called from the gate of Jihad; and (3) whoever was amongst those who used to observe fasts, will be called from the gate of al-Rayyan; and (4) whoever was amongst those who used to give in charity, will be called from the gate of charity."

Abu Bakr said, "Let my parents be sacrificed for you, O Messenger of Allah ﷺ! No distress or need will befall him who will be called from those gates. Will there be any one who will be called from all these gates?" The Prophet ﷺ replied, "Yes, and I hope you will be one of them."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ: «مَنْ أَنْفَقَ زَوْجَيْنِ فِي سَبِيلِ اللَّهِ نُودِيَ مِنْ أَبْوَابِ الْجَنَّةِ: يَا عَبْدَ اللَّهِ، هَذَا خَيْرٌ۔ (١) فَمَنْ كَانَ مِنْ أَهْلِ الصَّلاَةِ دُعِيَ مِنْ باب الصَّلاَةِ، (٢) وَمَنْ كَانَ مِنْ أَهْلِ الْجِهَادِ دُعِيَ مِنْ باب الْجِهَادِ، (٣) وَمَنْ كَانَ مِنْ أَهْلِ الصِّيَامِ دُعِيَ مِنْ باب الرَّيَّانِ، (٤) وَمَنْ كَانَ مِنْ أَهْلِ الصَّدَقَةِ دُعِيَ مِنْ باب الصَّدَقَةِ۔»

فَقَالَ أَبُو بَكْرٍ ؓ: بِأَبِي أَنْتَ وَأُمِّي يَا رَسُولَ اللَّهِ، مَا عَلَى مَنْ دُعِيَ مِنْ تِلْكَ الأَبْوَابِ مِنْ ضَرُورَةٍ۔ فَهَلْ يُدْعَى أَحَدٌ مِنْ تِلْكَ الأَبْوَابِ كُلِّهَا؟ قَالَ: «نَعَمْ، وَأَرْجُو أَنْ تَكُونَ مِنْهُمْ۔»
