وَعَنْ أَبِي سَعِيدٍ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى الله عَلَيْهِ وَسلم قَالَ: «من رَضِي بِاللَّه رَبًّا وَالْإِسْلَام دِينًا وَبِمُحَمَّدٍ رَسُولًا وَجَبَتْ لَهُ الْجَنَّةُ» . فَعَجِبَ لَهَا أَبُو سَعِيدٍ فَقَالَ: أَعِدْهَا عَلَيَّ يَا رَسُولَ اللَّهِ فَأَعَادَهَا عَلَيْهِ ثُمَّ قَالَ: «وَأُخْرَى يَرْفَعُ اللَّهُ بِهَا الْعَبْدَ مِائَةَ دَرَجَةٍ فِي الْجَنَّةِ مَا بَيْنَ كُلِّ دَرَجَتَيْنِ كَمَا بَيْنَ السَّمَاءِ وَالْأَرْضِ» . قَالَ: وَمَا هِيَ يَا رَسُولَ الله؟ قَالَ: «الْجِهَاد فِي سَبِيل الْجِهَادُ فِي سَبِيلِ اللَّهِ الْجِهَادُ فِي سَبِيلِ الله» . رَوَاهُ مُسلم

Abu Sa'id reported God’s Messenger as saying, “If anyone is pleased with God as Lord, with Islam as religion and with Muhammad as Messenger, paradise will be assured to him.” Abu Sa'id was delighted with this and asked him to repeat it. He did so and then said, “There is also something else for which God will raise a servant in paradise a hundred degrees between each two of which there is a distance like that between heaven and earth.” He asked God's Messenger what it was and he replied, “jihad in God's path; jihad in God’s path; jihad in God’s path.” Muslim transmitted it.
