They (hypocrites) are those of whom Allah knows what is in their hearts; so turn aside from them (do not punish them) but admonish them, and speak to them an effective word (i.e. to believe in Allah, worship Him, obey Him, and be afraid of Him) to reach their innerselves.
Meaning:-
Hypocrite:a person who pretends to have virtues, moral or religious beliefs, principles, etc., that he or she does not actually possess, especially a person whose actions belie stated beliefs.
