As for those who divide their religion and break up into sects, thou hast no part in them in the least: their affair is with God: He will in the end tell them the truth of all that they did. (6:159)

Those who split up their Religion, and become (mere) Sects,- each party rejoicing in that which is with itself! (30:32)

But sects from among themselves fell into disagreement: then woe to the wrong-doers, from the Penalty of a Grievous Day! (43:65)
