۞ لَّا خَيْرَ فِى كَثِيرٍۢ مِّن نَّجْوَىٰهُمْ إِلَّا مَنْ أَمَرَ بِصَدَقَةٍ أَوْ مَعْرُوفٍ أَوْ إِصْلَٰحٍۭ بَيْنَ ٱلنَّاسِ ۚ وَمَن يَفْعَلْ ذَٰلِكَ ٱبْتِغَآءَ مَرْضَاتِ ٱللَّهِ فَسَوْفَ نُؤْتِيهِ أَجْرًا عَظِيمًۭا
There is no good in much of their secret conferences save (in) him who enjoineth almsgiving and kindness and peace-making among the people. Whoso doeth that, seeking the good pleasure of Allah, We shall bestow on him a vast reward.
