86. This prayer was offered by Prophet Moses (peace be upon him) during the last period of his stay in Egypt. There was a long interval between this and the events mentioned in the preceding verse which happened during the early days of his mission. The details of this intervening period are available at other places in the Quran.
87. The Arabic word zeenat includes the magnificence, grandeur, glory and the apparent brilliance of their culture and civilization which attracted other people towards them with the desire of imitating them.
88. “Wealth”, possessions, resources and means which help the people like Pharaoh to put into practice all their devices and plans, and the lack of which prevents the standard bearers of the truth from carrying out their plans.
89. As it has already been stated, Prophet Moses (peace be upon him) made this prayer during the last period of his stay in Egypt. When he had shown many signs, one after the other, to Pharaoh and his chiefs and pointed out the way clearly to them, but they had persisted obdurately in their antagonism to the truth. The Prophet begged his Lord to destroy their possessions and harden their hearts. And this was in accordance with the decree of Allah. As they had merited this punishment according to the divine law of retribution, Allah decreed that they should not get the light of faith, which they themselves had extinguished with their persistent disbelief.
90. In this verse, Allah has urged Prophet Moses (peace be upon him) and his followers to guard against a common misunderstanding that is likely to arise in such cases. It so happens that those people who have no knowledge of the reality and who do not understand the wisdom of Allah’s ways are liable to believe from the apparent success of His rebels that perhaps it is His will that they should dominate in the world. When they witness the failures of the upholders of the truth in their conflict with falsehood in contrast to the splendor and vast possessions of the champions of falsehood, they begin to think that Allah does not will to help the truth in its conflict with falsehood. Therefore some foolish people further conclude from these wrong suppositions that it is useless to exert for the establishment of the truth. Then they consider it to be the best and most proper thing to rest content with the little religiosity that the sovereignty of falsehood and unbelief allows them. That is why Allah has urged Prophet Moses (peace be upon him) and his followers to guard against such a misunderstanding and to carry on the mission entrusted to them with patience under the adverse circumstances.
