The people of Makkah held the Prophet and his companions in contempt, and used to mock them. They did so due to their disbelief in the Hereafter and because in their hearts they were not fearful of God’s scourge; this made them quite flippant about the affairs of the Hereafter. The worst punishment for a man in this world is to be incapable of right thinking. One so punished is not capable of seeing things in their proper perspective. He is unable to learn lessons even from obvious realities. For example, innumerable stones of varying sizes, fall towards the Earth’s surface but get destroyed as soon as they come in contact with our atmosphere. If these stones were to start falling on human habitation, the entire humanity would be wiped out. A major part of the centre of the earth consists of hot molten lava. If that lava were to erupt and flow unchecked over the surface of the earth, everything in its path would be burnt to a cinder. But God, having made special arrangements, does not allow such catastrophic events to occur. There are clear signs in heaven and on earth which show man’s helplessness. But when a man is incapable of right thinking, no sign of God can give him guidance.
