COMMENTARY on 39:22
A. Yusuf Ali:

Translation:
Is one whose heart Allah has opened to Islam, 4274 so that he has received Enlightenment from Allah, (no better than one hard-hearted)? Woe to those whose hearts are hardened against celebrating 4275 the praises of Allah. they are manifestly wandering (in error)!
Commentary:

4274  Those who listen to Allah's Message find at each stage Allah's Grace helping them more and more to expand their spiritual understanding and to receive Allah's light, so that they travel farther and farther to their Goal in the Path of Truth and Righteousness. They are not to be compared to those who shut out Allah's Light from their hearts. See next note.

4275  Just as there is spiritual progress for those who seek Allah, so there is more and more spiritual retrogression for those who close their hearts to Allah. Their hearts get hardened, and they allow less and less Allah's Grace to penetrate within. But it is obvious that they flounder on the Way, and cannot walk with the firm steps of those of assured Faith.
