And We ordained laws for him in the tablets in all matters both commanding and explaining all things (and said): "take and hold these with firmness and enjoin thy people to hold fast by the best in the precepts: soon shall I show you the homes of the wicked (how they lie desolate)." 1107 1108 1109
The Tablets of the Law contained the essential Truth, from which were derived the positive injunctions and prohibitions, explanations and interpretations, which it was the function of the prophetic office to hold up for the people to follow. The precepts would contain, as the Shari'at does, matters absolutely prohibited, matters not prohibited but disapproved, matters about which there was no prohibition or injunction, but in which conduct was to be regulated by circumstances; matters of positive and universal duty, matters recommended for those whose zeal was sufficient to enable them to work on higher than minimum standards. No soul is burdened beyond its capacity; but we are asked to seek the best and highest possible for us in conduct.
Notice the transition from the "We" of authority and honour and impersonal dignity, to the "I" of personal concern in specially guiding the righteous.
Literally, the homes of the wicked, both individuals and nations, lie desolate, as in the case of the ancient Egyptians, the 'Ad, and the Thamud.
