question #3 Sahih al-Bukhari 7460, Book 97, Hadith 86 : What is the significance of remaining steadfast in faith until the arrival of the Hour?

I heard the Prophet (ﷺ) saying, “A group of my followers will keep on following Allah’s Laws strictly and
they will not be harmed by those who will disbelieve them or stand against them till Allah’s Order
(The Hour) will come while they will be in that state.”
