COMMENTARY on 4:134
A. Yusuf Ali:

Translation:
If any one desires a reward in this life, in Allah.s (gift) is the reward (both) of this life and of the Hereafter; 643 for Allah is He that heareth and seeth (all things).
Commentary:

643  Man in this life can only see up to the horizon of this life. The highest rewards which his wishes or ambitions can conceive of are conceived in the terms of this life. But Allah can give him not only these but something infinitely higher—the rewards of the He re after-which it did not even enter his heart to ask for or his imagination to conceive.
