Chapter: 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

باب نُزُولِ عِيسَى ابْنِ مَرْيَمَ حَاكِمًا بِشَرِيعَةِ نَبِيِّنَا مُحَمَّدٍ صلى الله عليه وسلم

Jabir b. 'Abdullah reported:

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.
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 ‏"‏ ‏.‏
