ethical speech

وَلْيَخْشَ ٱلَّذِينَ لَوْ تَرَكُوا۟ مِنْ خَلْفِهِمْ ذُرِّيَّةً ضِعَـٰفًا خَافُوا۟ عَلَيْهِمْ فَلْيَتَّقُوا۟ ٱللَّهَ وَلْيَقُولُوا۟ قَوْلًا سَدِيدًا

And let those [executors and guardians] fear [injustice] as if they [themselves] had left weak offspring behind and feared for them. So let them fear Allāh and speak words of appropriate justice.

۞ لَّا خَيْرَ فِى كَثِيرٍ مِّن نَّجْوَىٰهُمْ إِلَّا مَنْ أَمَرَ بِصَدَقَةٍ أَوْ مَعْرُوفٍ أَوْ إِصْلَـٰحٍۭ بَيْنَ ٱلنَّاسِ ۚ وَمَن يَفْعَلْ ذَٰلِكَ ٱبْتِغَآءَ مَرْضَاتِ ٱللَّهِ فَسَوْفَ نُؤْتِيهِ أَجْرًا عَظِيمًا

No good is there in much of their private conversation, except for those who enjoin charity or that which is right or conciliation between people. And whoever does that seeking means to the approval of Allāh - then We are going to give him a great reward.
