quran:58:9

O you who have believed, when you converse privately, do not converse about sin and aggression and disobedience to the Messenger but converse about righteousness and piety. And fear Allah, to whom you will 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.
القرآن:٥٨:٩

يَا أَيُّهَا الَّذِينَ آمَنُوا إِذَا تَنَاجَيْتُمْ فَلَا تَتَنَاجَوْا بِالْإِثْمِ وَالْعُدْوَانِ وَمَعْصِيَتِ الرَّسُولِ وَتَنَاجَوْا بِالْبِرِّ وَالتَّقْوَىٰ ۖ وَاتَّقُوا اللَّهَ الَّذِي إِلَيْهِ تُحْشَرُونَ  

{يا أيها الذين آمنوا إذا تناجيتم فلا تتناجوا بالإثم والعدوان ومعصية الرسول وتناجوا بالبر والتقوى واتقوا الله الذي إليه تحشرون}.
