Overview (Verses 57 - 59)

The truth is clear, but the unbelievers resorted to false arguments, trying to disprove the truth. Their attitude was perverted, because even when they demanded miracles or hastened God’s punishment, they still did not wish to be convinced. Essentially they were only ridiculing God’s revelations and mocking His messengers.
 
Who could be more wicked than one who, when reminded of his Lord’s revelations, turns away from them and forgets what his own hands have done? Over their hearts We have cast veils which prevent them from grasping the truth, and into their ears, deafness. Even if you call them to the right path, they shall never be guided. (Verse 57) These people who treat what God has bestowed from on high with mockery and who ridicule His warnings cannot understand the Qur’ān or comprehend its message. Hence, God places over their hearts screens which prevent them from understanding it. In their ears He causes a sort of deafness so that they cannot hear it. He has also willed that, because of their deliberate refusal and wilful turning away from His guidance, they will never be guided. For guidance to penetrate people’s hearts, such hearts must be open to receive it in the first place.
 
“Your Lord is Most Forgiving, limitless in His grace. Were He to take them now to task for whatever they do, He would indeed bring about their speedy punishment.” (Verse 58) Rather, He gives them respite and allows them time, because He is Kind and Merciful. He wishes to allow them every chance so that they can see the issues clearly. He does not hasten their punishment as they demand. However, He will not abandon them completely and leave them unpunished: “But they have an appointed time which they cannot evade.” (Verse 58) They have a term in this life which they will fulfil. During this time a portion of their punishment will be inflicted on them. And they have a time appointed in the hereafter when whatever they have deserved will be given in full.
 
They have done wrong and they have been unjust. Hence they deserve punishment, or even destruction in the same way as communities of old. However, God in His mercy has determined to give them a chance for the full duration of their term on earth. That is to fulfil a purpose which He, in His wisdom, wishes to be accomplished. Therefore, He treats them differently and allows them respite until the time appointed for them, which they cannot evade: The same applied to other communities which We destroyed when they persisted in wrongdoing. For We had set a time for their destruction. (Verse 59) They must not be deluded by the respite they are given. Their time will inevitably come. The rules God has made applicable will never fail, and He does not leave any promise unfulfilled.
