"In Paradise, there are a hundred levels, between every two levels is (the distance of) a hundred years."  

قَالَ رَسُولُ اللَّهِ ﷺ فِي الْجَنَّةِ مِائَةُ دَرَجَةٍ مَا بَيْنَ كُلِّ دَرَجَتَيْنِ مِائَةُ عَامٍ  

"Whoever fasts Ramadan, performs the Salat, performs Hajj to the House" - I do not know whether he mentioned Zakat or not - "except that it is binding on Allah that He forgive him, whether he emigrated in the cause of Allah, or remained in his land in which he was born." Mu'adh said: "Should I not inform the people of this?" The Messenger of Allah ﷺ said, "Leave the people to do deeds, for verily in Paradise there are a hundred levels, what is between every two levels is like what is between the heavens and the earth. Al-Firdaus is the highest of Paradise and its most expansive, and above that is the Throne of Ar-Rahman (the Most Merciful), and from it the rivers of Paradise are made to flow forth. So when you ask Allah, ask Him for Al-Firdaus."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَنْ صَامَ رَمَضَانَ وَصَلَّى الصَّلَوَاتِ وَحَجَّ الْبَيْتَ لاَ أَدْرِي أَذَكَرَ الزَّكَاةَ أَمْ لاَ إِلاَّ كَانَ حَقًّا عَلَى اللَّهِ أَنْ يَغْفِرَ لَهُ إِنْ هَاجَرَ فِي سَبِيلِ اللَّهِ أَوْ مَكَثَ بِأَرْضِهِ الَّتِي وُلِدَ بِهَا قَالَ مُعَاذٌ أَلاَ أُخْبِرُ بِهَذَا النَّاسَ فَقَالَ رَسُولُ اللَّهِ ﷺ ذَرِ النَّاسَ يَعْمَلُونَ فَإِنَّ فِي الْجَنَّةِ مِائَةَ دَرَجَةٍ مَا بَيْنَ كُلِّ دَرَجَتَيْنِ كَمَا بَيْنَ السَّمَاءِ وَالأَرْضِ وَالْفِرْدَوْسُ أَعْلَى الْجَنَّةِ وَأَوْسَطُهَا وَفَوْقَ ذَلِكَ عَرْشُ الرَّحْمَنِ وَمِنْهَا تُفَجَّرُ أَنْهَارُ الْجَنَّةِ فَإِذَا سَأَلْتُمُ اللَّهَ فَسَلُوهُ الْفِرْدَوْسَ  

"In Paradise, there are a hundred levels, what is between every two levels is like what is between the heavens and the earth. Al-Firdaus is ts highest level, and from it the four rivers of Paradise are made to flow forth. So when you ask Allah, ask Him for Al-Firdaus." Another chain reports a similar narration.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ فِي الْجَنَّةِ مِائَةُ دَرَجَةٍ مَا بَيْنَ كُلِّ دَرَجَتَيْنِ كَمَا بَيْنَ السَّمَاءِ وَالأَرْضِ وَالْفِرْدَوْسُ أَعْلاَهَا دَرَجَةً وَمِنْهَا تُفَجَّرُ أَنْهَارُ الْجَنَّةِ الأَرْبَعَةُ وَمِنْ فَوْقِهَا يَكُونُ الْعَرْشُ فَإِذَا سَأَلْتُمُ اللَّهَ فَسَلُوهُ الْفِرْدَوْسَ حَدَّثَنَا أَحْمَدُ بْنُ مَنِيعٍ حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ حَدَّثَنَا هَمَّامٌ عَنْ زَيْدِ بْنِ أَسْلَمَ نَحْوَهُ  

"Indeed there are a hundred levels in Paradise, if all of the People of Paradise were to be gathered in one of them, it would have sufficed them."  

عَنِ النَّبِيِّ ﷺ قَالَ إِنَّ فِي الْجَنَّةِ مِائَةَ دَرَجَةٍ لَوْ أَنَّ الْعَالَمِينَ اجْتَمَعُوا فِي إِحْدَاهُنَّ لَوَسِعَتْهُمْ
