COMMENTARY on 4:169
A. Yusuf Ali:

Translation:
Except the way of Hell, to dwell therein for ever. And this to Allah is easy. 673
Commentary:

673  Easy-not in the sense that Allah takes any pleasure in any of His creatures going astray. The contrary is the case: for Allah's Grace recognises all good in us to such an extent that it is compared to gratitude in 4:147; see n. 653. We must understand easy in the sense that Allah is Supreme in knowledge and power; if any forces of rebellion foolishly think that they can evade punishment, they are mistaken. Punishment comes as a matter of course. It is not a matter of difficulty or exertion on the part of Allah.
