And whoever commits a sin only earns it against himself. And Allah is ever Knowing and Wise.
وَلَوْلَا فَضْلُ ٱللَّهِ عَلَيْكَ وَرَحْمَتُهُۥ لَهَمَّت طَّآئِفَةٌ مِّنْهُمْ أَن يُضِلُّوكَ وَمَا يُضِلُّونَ إِلَّآ أَنفُسَهُمْ ۖ وَمَا يَضُرُّونَكَ مِن شَىْءٍ ۚ وَأَنزَلَ ٱللَّهُ عَلَيْكَ ٱلْكِتَـٰبَ وَٱلْحِكْمَةَ وَعَلَّمَكَ مَا لَمْ تَكُن تَعْلَمُ ۚ وَكَانَ فَضْلُ ٱللَّهِ عَلَيْكَ عَظِيمًا
And if it was not for the favor of Allah upon you, [O Muhammad], and His mercy, a group of them would have determined to mislead you. But they do not mislead except themselves, and they will not harm you at all. And Allah has revealed to you the Book and wisdom and has taught you that which you did not know. And ever has the favor of Allah upon you been great.
۞ 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 Allah - then We are going to give him a great reward.
