Translation:

176. (Their doom is) because Allah sent down the Book in truth but those who seek causes of dispute in the Book are in a schism far (from the purpose).

Notes (Tafseer)

176. From the mere physical regulation we are at once lifted up into the sphere of morals and faith. For the one acts and reacts on the other. If we are constantly carping at wholesome regulations, we shall do nothing but cause division and schisms among the people, and ordered society would tend to break up.
