Overall meaning : Have you not seen, Muhammad, those who, though forbidden to confer secretly among themselves with wickedness, persistently do what they were forbidden to do and continue to confer together secretly to commit sins and transgressions and to show disobedience to you? When they come to you, they do not salute you with the greeting of peace with which Allah salutes you, and secretly say, ‘Why does Allah not hasten to punish us in this life for what we say to Muhammad?’ Sufficient for them will be Hell, which they will enter to suffer its punishment—an evil destination indeed!
Believers, when you confer together secretly, do not do so to commit sins and transgressions and to show disobedience to the Messenger; rather, confer privately to work righteousness, to do what Allah commands and to avoid what He forbids; and fear Allah, before whom you will all be gathered together.
Holding secret counsels with evil intentions is the work of Satan, who only seeks thereby to fill the believers’ hearts with grief and distress. Yet he cannot harm them in the least except by Allah’s will. The true believers must put their trust in none but Allah alone
