Commentary
The above verses state the imperfection and temporary nature of the blessings of this world, as against the perfection and permanence of the blessings of the Hereafter. The most important and major condition for obtaining the heavenly blessings in the Hereafter is faith and belief, without which nobody can get them. However, if in addition to faith, one has taken full care of virtuous deeds as well, then one will get the heavenly blessings right from the beginning, otherwise one would get them after being punished for one's sins and shortcomings. That is why the first condition stated in the above verses is belief referred to by the words, "those who believe". Then those particular deeds have been stated without which, according to the rule, the bounties of the Hereafter will not be obtained from the beginning, but after having been punished for one's sins. The rule is there for application in general, but if Allah Ta’ ala wills, He may forgive all the sins of the greatest of the sinners, and give him the blessings of the Hereafter right from the beginning, He is not subject to any rule or code. Now, let us look at those particular virtues and deeds which have been mentioned with such an importance.
First virtue: عَلَىٰ رَبِّهِمْ يَتَوَكَّلُونَ (and place their trust in Allah - 36,) meaning those who place their trust in Allah, under all circumstances, in all matters; they do not consider anyone else to be the real cause of anything.
