The realities declared on behalf of God, are all perfectly rational and reasonable. If a man pays attention to them, he can easily understand them. So why do people reject them? The reason for this is people’s disbelief in the Hereafter. People do not earnestly and actively believe that they will have to face any reckoning in the Hereafter. So, they are not serious about these matters and as such they are unable to understand them. If a man has a firm belief in the reward for good deeds, he will immediately understand matters which he hitherto found extremely difficult to appreciate.
