237.Allah has prescribed certain obligations for you, so do not neglect them; He has defined certain limits, so do not transgress them; He has prohibited certain things, so do not do them; and He has kept silent concerning other things out of mercy for you and not because of forgetfulness, so do not ask questions concerning them.
