Narrated AbuHurayrah: The Prophet ﷺ said: The Jews were split up into seventy-one or seventy-two sects; and the Christians were split up into seventy one or seventy-two sects; and my community will be split up into seventy-three sects.
The Prophet Muhammad taught us through this hadith that we should strive for unity in our communities and respect each other's differences in opinion without judging or criticizing them. We should also remember that it is only Allah who knows what is truly right and wrong, so we should leave judgment up to Him alone.
