(53) باب قَوْلِهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لاَ تَزَالُ طَائِفَةٌ مِنْ أُمَّتِي ظَاهِرِينَ عَلَى الْحَقِّ لاَ يَضُرُّهُمْ مَنْ خَالَفَهُمْ»
It has been narrated on the authority of Jabir b. Samura that the Prophet (ﷺ) said:
This religion will continue to exist, and a group of people from the Muslims will continue to fight for its protection until the Hour is established.
