Sahih Muslim 156
Sahih Muslim · Book 1: The Book of Faith · The descent of 'Eisa bin Mariam to judge according to the Shari'ah of our Prophet Muhammad (saws); And how Allah has honored this Ummah; And clarifying the evidence that this religion will not be abrogated; and that a group from it will continue to adhere to the truth and prevail until the day of resurrection
Jabir b. 'Abdullah reported:
حَدَّثَنَا الْوَلِيدُ بْنُ شُجَاعٍ ، وَهَارُونُ بْنُ عَبْدِ اللَّهِ ، وَحَجَّاجُ بْنُ الشَّاعِرِ ، قَالُوا حَدَّثَنَا حَجَّاجٌ، - وَهُوَ ابْنُ مُحَمَّدٍ - عَنِ ابْنِ جُرَيْجٍ ، قَالَ أَخْبَرَنِي أَبُو الزُّبَيْرِ ، أَنَّهُ سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ ، يَقُولُ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ " لاَ تَزَالُ طَائِفَةٌ مِنْ أُمَّتِي يُقَاتِلُونَ عَلَى الْحَقِّ ظَاهِرِينَ إِلَى يَوْمِ الْقِيَامَةِ - قَالَ - فَيَنْزِلُ عِيسَى ابْنُ مَرْيَمَ صلى الله عليه وسلم فَيَقُولُ أَمِيرُهُمْ تَعَالَ صَلِّ لَنَا . فَيَقُولُ لاَ . إِنَّ بَعْضَكُمْ عَلَى بَعْضٍ أُمَرَاءُ . تَكْرِمَةَ اللَّهِ هَذِهِ الأُمَّةَ " .
I heard the Messenger of Allah (ﷺ) say: A section of my people will not cease fighting for the Truth and will prevail till the Day of Resurrection. He said: Jesus son of Mary would then descend and their (Muslims') commander would invite him to come and lead them in prayer, but he would say: No, some amongst you are commanders over some (amongst you). This is the honour from Allah for this Ummah.
