Overall meaning : Some of these—who take their fill of pleasure in this world and eat as the beasts eat and to whom their evil deeds are decked out fair—indeed listen to you (that is, the hypocrites), but as soon as they leave your presence, they mockingly ask those endowed with knowledge among your companions who have attended your gathering, ‘What did he say just now?’
These are they whose hearts Allah has sealed up and thus do not believe, and who follow their own desires by embracing unbelief and rejecting of the truth. As for those who believe the truth and follow it, the Qur’an and the Prophet’s words to which they listen only increase and strengthen their faith, and Allah will inspire them to obey His commands and avoid what He forbids.
What are these hypocrites awaiting other the Day of Judgement to take them unawares? Now indeed its portents have already come. But how can admonition benefit them if Judgement Day overtakes them suddenly?!
Know, therefore, Muhammad, that there is no god worthy of worship but Allah. Ask Him to forgive your sins and to forgive the sins of all believing men and women. Allah is fully aware of all your movements, people, and your place of rest.
