Surah 37. As-Saffat, Ayah 147

The city of Nineveh was a very large city. Tbe Old Testament says: "Nineveh was an exceeding great city of three days' journey" (Jonah, iii. 3); "wherein are more than six score thousand persons" (Jonah, iv. 11). In other words its circuit was about 45 miles, and its population was over a hundred and twenty thousand inhabitants.
