Quran 30:31 — The Romans (Al-Room)

You shall submit to Him, reverence Him, observe the Contact Prayers (Salat), and—whatever you do—do not ever fall into idol worship.

[30:30] Therefore, you shall devote yourself to the religion of strict monotheism. Such is the natural instinct placed into the people by GOD. Such creation of GOD will never change. This is the perfect religion, but most people do not know.

[30:32] (Do not fall in idol worship,) like those who divide their religion into sects; each party rejoicing with what they have.
