As is shown by the hadeeth of at-Tirmidhee (no. 2641): 'Abdullaah ibn 'Amr said: The Messenger of Allaah said,"What happened to the Children of lsraa'eel will happen with my Ummah, just as one shoe resembles the other, to the point that if one of them had intercourse with his mother openly, there would be someone who did that in my Ummah. The Children of Israa'eel split into seventy two sects and my Ummah will split into seventy three sects, all of which are in the Fire except one sect." They asked, "Which is that one, 0 Messenger of Allaah?" He replied, "That which I and my Companions are upon." Declared hasan by Shaikh al-Albaanee.
