The fifth verse refers to the hypocrites under the same issue and the verse says, “Do they not know that god knows their hidden thoughts and their secret whisperings and that God is the great Knower?”
The term “Knower of the Unseen” is a new terminology because the word Allam is a hyperbole and unseen is a common word that includes everything that which is normal and that which is extraordinary. The strange fact is that till now all the verses warn mankind that they should watch their deeds and be careful of how and what they speak and think or intend. They all first speak of the culturing of mankind.
Najwa means a lofty edifice. When a person wants to discuss some secret he moves away from people and this word is used for whisperings also.
