Sahih Muslim 1925
Sahih Muslim · Book 33: The Book on Government · The words of the prophet saws: "A Group of my Ummah will continue to Prevail on the basis of the Truth, and They will not be Harmed by those who oppose them."
It has been narrated by Sa'd b. Abu Waqqas that the Messenger of Allah (ﷺ) said:
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى ، أَخْبَرَنَا هُشَيْمٌ ، عَنْ دَاوُدَ بْنِ أَبِي هِنْدٍ ، عَنْ أَبِي عُثْمَانَ ، عَنْ سَعْدِ بْنِ أَبِي وَقَّاصٍ ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ يَزَالُ أَهْلُ الْغَرْبِ ظَاهِرِينَ عَلَى الْحَقِّ حَتَّى تَقُومَ السَّاعَةُ " .
The people of the West will continue to triumphantly follow the truth until the Hour is established.
