﴿ يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِذَا تَنَٰجَيْتُمْ فَلَا تَتَنَٰجَوْا۟ بِٱلْإِثْمِ وَٱلْعُدْوَٰنِ وَمَعْصِيَتِ ٱلرَّسُولِ وَتَنَٰجَوْا۟ بِٱلْبِرِّ وَٱلتَّقْوَىٰ ۖ وَٱتَّقُوا۟ ٱللَّهَ ٱلَّذِىٓ إِلَيْهِ تُحْشَرُونَ ﴾

“[Hence,] O you who have attained to faith, when you do hold secret confabulations, do not conspire with one another with a view to sinful doings, and aggressive conduct, and disobedience to the Apostle, but [rather] hold counsel in the cause of virtue and God-consciousness: and [always] remain conscious of God, unto whom you all shall be gathered.”

O you who believe if you do talk in secret then do not talk in secret sinfully and in enmity and disobedience to the Messenger but talk secretly in piety and fear of God. And fear God to Whom you will be gathered.
