Surah 6. Al-An'am, Ayah 47

Lit., "Can you see yourselves".

I.e., the righteous will never be really "destroyed" - for, even if they should suffer physical destruction, they are bound to attain to spiritual bliss and cannot, therefore, be said to have been "destroyed" like the evildoers, who, by their actions, lose their happiness both in this world and in the life to come (Razi).

Suddenly=without warning. Openly=with many warnings, even to the sinners, though they heed them not. As to those who understand and read the signs of God, they could always tell that all wrong-doing must eventually have its punishment. But it will affect the wrong-doers, not the righteous. It is justice, not revenge.
