The Prophet ﷺ said, "This religion will continue to stand firm, with a band of Muslims fighting for it, until the Hour comes."
عن النبي ﷺ أنه قال: لن يبرح هذا الدين قائما، يقاتل عليه عصابة من المسلمين حتى تقوم الساعة.
Muslim narrated it in the book of leadership (1922), through the route of Muhammad bin Jafar, who said, Shuba narrated to us, from Simak bin Harb, from Jabir bin Samura, and he related it.
