[4:134] Whoever desires the reward of this world, then God has the reward of this world and of the Hereafter; God is ever Hearer, Seer.
When they attach their hearts to what is immediate in this world, He reminded them of the event of the Hereafter, and said: then God has the reward of this world and of the Hereafter. This was to inform them that above their aspirations for this paltry thing there is something higher than it in the blessing of the Hereafter. When their objectives were elevated to the Hereafter, He cut them off from any external sign and created thing by His saying: And God is better and more enduring [20:73].
