﴿ 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.”
