And We shall try you until We test those among you who strive their utmost and persevere in patience; and We shall try your reported (mettle).
The test and trial is for our own psychological
development, to help in the exercise of such choice as
has been given to us in our free- will.
Akhbar: the things reported of you; reputation
for courage and constancy, which has to be brought to
the test of facts and experience.
In an epigram of Tacitus we are told of a Roman
Emperor that he would have been considered in every
way to have been worthy of being a ruler if only he had
never ruled! So in life people may think us courageous,
true, noble, and self-sacrificing; and we may consider
ourselves as possessing all such virtues; but it is actual
experience that will bring them to the test.
