It is narrated that the Prophet ﷺ once said:
"No doubt, the people of the Book before you split into seventy-two sects and this religion will split into seventy-three sects, seventy-two will be in the Hellfire and one will be in Paradise. It is the united community. Verily, there will emerge people in my nation who will be infected by these vain desires, just as rabies from a dog infects its patient."
It is extremely important to study the reasons why the previous people split into groups, according to the Quran, and make sure we don't fall into this.
