Topics discussed in this Verse:
[Children of Israel:hearts went wrong] [Moses:vexed and insulted _ but honourable]

Now when Moses spoke to his people, [it was this same truth that he had in mind:] "O my people! Why do you cause me grief, the while you know that I am an apostle of God sent unto you?" And so, when they swerved from the right way, God let their hearts swerve from the truth: for God does not bestow His guidance upon iniquitous folk. - 61:5 (Asad) -
