Quran 84:23

But God knows what they harbour in their breasts.

and Allah knows best what they keep to themselves.

And Allah well knows what they conceal in their hearts.

and God knows very well what they are secreting.

And Allah (is) most knowing of what they keep within themselves

Whereas Allah knoweth best that which they cherish.

And Allah knows best what they gather (of good and bad deeds),

Allah knows best what they are accumulating (in their Record).

but God knows best whatever they accumulate in their hearts.

And Allah knows best what they hide,

And Allah knoweth best what they are hiding.

and Allah knows very well what they gather.

And Allah is most knowing of what they keep within themselves.

But God knows what they hide inside.

God is quite aware of what they are storing in their hearts.

But Allah has full knowledge of what they secrete (in their breasts)
