Sunan an-Nasa'i 3131
It was narrated from Abu Sa'eed Al-Khudri that the Messenger of Allah (ﷺ) said:
"O Abu Sa'eed! Whoever is content with Allah as Lord, Islam as his religion and Muhammad as Prophet, then he is guaranteed Paradise." Abu Sa'eed found this amazing and said: "Say it to me again, O Messenger of Allah." So he did that, then the Messenger of Allah (ﷺ) said: "And there is something else by means of which a person may be raised one hundred degrees in Paradise, each of which is like that which is between the Heaven and the Earth." He said: "What is it, O Messenger of Allah?" He said: "Jihad in the cause of Allah, Jihad in the cause of Allah."
قَالَ الْحَارِثُ بْنُ مِسْكِينٍ قِرَاءَةً عَلَيْهِ وَأَنَا أَسْمَعُ، عَنِ ابْنِ وَهْبٍ، قَالَ حَدَّثَنِي أَبُو هَانِئٍ، عَنْ أَبِي عَبْدِ الرَّحْمَنِ الْحُبُلِيِّ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ يَا أَبَا سَعِيدٍ مَنْ رَضِيَ بِاللَّهِ رَبًّا وَبِالإِسْلاَمِ دِينًا وَبِمُحَمَّدٍ نَبِيًّا وَجَبَتْ لَهُ الْجَنَّةُ ‏"‏ ‏.‏ قَالَ فَعَجِبَ لَهَا أَبُو سَعِيدٍ قَالَ أَعِدْهَا عَلَىَّ يَا رَسُولَ اللَّهِ ‏.‏ فَفَعَلَ ثُمَّ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ وَأُخْرَى يُرْفَعُ بِهَا الْعَبْدُ مِائَةَ دَرَجَةٍ فِي الْجَنَّةِ مَا بَيْنَ كُلِّ دَرَجَتَيْنِ كَمَا بَيْنَ السَّمَاءِ وَالأَرْضِ ‏"‏ ‏.‏ قَالَ وَمَا هِيَ يَا رَسُولَ اللَّهِ قَالَ ‏"‏ الْجِهَادُ فِي سَبِيلِ اللَّهِ الْجِهَادُ فِي سَبِيلِ اللَّهِ ‏"‏ ‏.‏
