‘He is the one who knows everything in the seven heavens and the seven earths and whatever is between them and whatever is beneath the ground and whatever is in the depths of the oceans. Who knows the place where every hair grows, where every tree is, each leaf that falls, the number of stones there are, the number of grains of sand there are, the amount of soil, the weight of the mountains, all of the actions of the servants (and the traces they leave behind) and their speech and every breath they take. He knows everything - nothing is hidden from Him - whilst He is upon the throne above the seven heavens. He the perfect and Most High’. He knows whatever was, whatever is and whatever will be before it occurs and He knows the true and hidden reality of everything. He knows whatever is not going to be and how it would be (if it were to exist) and He has always been the all knowing, perfect in His knowledge.
