Al-Mujadila 58:9 يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓاْ إِذَا تَنَٰجَيۡتُمۡ فَلَا تَتَنَٰجَوۡاْ بِٱلۡإِثۡمِ وَٱلۡعُدۡوَٰنِ وَمَعۡصِيَتِ ٱلرَّسُولِ وَتَنَٰجَوۡاْ بِٱلۡبِرِّ وَٱلتَّقۡوَىٰۖ وَٱتَّقُواْ ٱللَّهَ ٱلَّذِىٓ إِلَيۡهِ تُحۡشَرُونَ O you who believe! When you hold secret counsel, do it not for sin and wrong-doing, and disobedience towards the Messenger (Muhammad صلى الله عليه وسلم), but do it for Al-Birr (righteousness) and Taqwā (virtues and piety); and fear Allāh unto Whom you shall be gathered. Translation: Muḥsin Khān/Taqī-ud-Dīn-al-Hilālī ‎—————— Imām As-Saʿdī Commented: Private conversation is a conversation between two or more people. It may be a discussion about something good or something evil. Allah ( سبحانه و تعالى) instructs the believers to converse in righteousness, which includes all kinds of goodness, obedience, fulfilling duties towards Allah and His slaves, and righteousness and piety, which here refers to refraining from all kinds of forbidden and sinful actions. The believer complies with this divine command, so you will not find him conversing or talking about anything but that which brings him closer to Allah and keeps him away from that which incurs His wrath. The evildoer takes the command of Allah lightly, and converses in sin and transgression, and in enmity and disobedience towards the Messenger (ﷺ), as the hypocrites did all the time with the Messenger (ﷺ). ‎—————— 𝗦𝗼𝘂𝗿𝗰𝗲: [Taysīr al-Karīm ar-Rahmān fī Tafsīr Kalām al-Mannān, Vol.10, pg 35-36] https://salafibookstore.com/product/tafseer-as-sadi-10-volumes/
