Narrated Abu Huraira:The Prophet (ﷺ) said, "Whoever believes in Allah and His Apostle offers prayers perfectly and fasts (the month of) Ramadan then it is incumbent upon Allah to admit him into Paradise, whether he emigrates for Allah's cause or stays in the land where he was born." They (the companions of the Prophet) said, "O Allah's Messenger (ﷺ)! Should we not inform the people of that?" He said, "There are one-hundred degrees in Paradise which Allah has prepared for those who carry on Jihad in His Cause. The distance between every two degrees is like the distance between the sky and the Earth, so if you ask Allah for anything, ask Him for the Firdaus, for it is the last part of Paradise and the highest part of Paradise, and at its top there is the Throne of Beneficent, and from it gush forth the rivers of Paradise."
حَدَّثَنَا إِبْرَاهِيمُ بْنُ الْمُنْذِرِ، حَدَّثَنِي مُحَمَّدُ بْنُ فُلَيْحٍ، قَالَ حَدَّثَنِي أَبِي، حَدَّثَنِي هِلاَلٌ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " مَنْ آمَنَ بِاللَّهِ وَرَسُولِهِ، وَأَقَامَ الصَّلاَةَ، وَصَامَ رَمَضَانَ، كَانَ حَقًّا عَلَى اللَّهِ أَنْ يُدْخِلَهُ الْجَنَّةَ هَاجَرَ، فِي سَبِيلِ اللَّهِ، أَوْ جَلَسَ فِي أَرْضِهِ الَّتِي وُلِدَ فِيهَا ". قَالُوا يَا رَسُولَ اللَّهِ أَفَلاَ نُنَبِّئُ النَّاسَ بِذَلِكَ. قَالَ " إِنَّ فِي الْجَنَّةِ مِائَةَ دَرَجَةٍ أَعَدَّهَا اللَّهُ لِلْمُجَاهِدِينَ فِي سَبِيلِهِ، كُلُّ دَرَجَتَيْنِ مَا بَيْنَهُمَا كَمَا بَيْنَ السَّمَاءِ وَالأَرْضِ، فَإِذَا سَأَلْتُمُ اللَّهَ فَسَلُوهُ الْفِرْدَوْسَ، فَإِنَّهُ أَوْسَطُ الْجَنَّةِ وَأَعْلَى الْجَنَّةِ، وَفَوْقَهُ عَرْشُ الرَّحْمَنِ، وَمِنْهُ تَفَجَّرُ أَنْهَارُ الْجَنَّةِ ".
