The description of a day equaling 1000 years is the Quran’s eloquent way of describing Allah’s Greatness versus our smallness. It means whatever they whatever measure of time they calculate or imagine, it is only as one day (or less) in Allah’s evaluation. It is nothing. They measure distances in light years – that is a measure of distance based on time – the time light, traveling at 300,000 kilometers per second, travels in one year. They speak of galactic distances of millions, even billions of light years. According to what they measure it is great, but to Allah it is nothing.
