The word(s) "sect" appears 18 time(s) in 16 verse(s) in Quran in Mohsin Khan translation.

(11) Verily, your Lord will decide between them (various sects) by His Judgement. And He is the All-Mighty, the All-Knowing.

(12) Verily, Fir'aun (Pharaoh) exalted himself in the land and made its people sects, weakening (oppressing) a group (i.e. Children of Israel) among them: killing their sons, and letting their females live. Verily, he was of the Mufsidun (i.e. those who commit great sins and crimes, oppressors, tyrants).

(13) Of those who split up their religion (i.e. who left the true Islamic Monotheism), and became sects, [i.e. they invented new things in the religion (Bid'ah ), and followed their vain desires], each sect rejoicing in that which is with it.

(14) He (Allah) has ordained for you the same religion (Islamic Monotheism) which He ordained for Nuh (Noah), and that which We have revealed to you (O Muhammad صلى الله عليه و سلم), and that which We ordained for Ibrahim (Abraham), Musa (Moses) and 'Îsa (Jesus) saying you should establish religion (i.e. to do what it orders you to do practically), and make no divisions in it (religion) (i.e. various sects in religion). Intolerable for the Mushrikun, is that (Islamic Monotheism) to which you (O Muhammad صلى الله عليه و سلم) call them. Allah chooses for Himself whom He wills, and guides unto Himself who turns to Him in repentance and in obedience.

(15) But the sects from among themselves differed. So woe to those who do wrong [by ascribing things to 'Îsa (Jesus) that are not true] from the torment of a painful Day (i.e. the Day of Resurrection)!

(16) 'There are among us some that are righteous, and some the contrary; we are groups having different ways (religious sects).
