An-Nisa 4:111

يَسْتَخْفُونَ مِنَ النَّاسِ وَلَا يَسْتَخْفُونَ مِنَ اللَّهِ وَهُوَ مَعَهُمْ إِذْ يُبَيِّتُونَ مَا لَا يَرْضَىٰ مِنَ الْقَوْلِ ۚ وَكَانَ اللَّهُ بِمَا يَعْمَلُونَ مُحِيطًا

They conceal [their evil intentions and deeds] from the people, but they cannot conceal [them] from Allah, and He is with them [in His knowledge] when they spend the night in such as He does not accept of speech. And ever is Allah, of what they do, encompassing.

هَا أَنتُمْ هَـٰؤُلَاءِ جَادَلْتُمْ عَنْهُمْ فِي الْحَيَاةِ الدُّنْيَا فَمَن يُجَادِلُ اللَّهَ عَنْهُمْ يَوْمَ الْقِيَامَةِ أَم مَّن يَكُونُ عَلَيْهِمْ وَكِيلًا

Here you are - those who argue on their behalf in [this] worldly life - but who will argue with Allah for them on the Day of Resurrection, or who will [then] be their representative?

وَمَن يَعْمَلْ سُوءًا أَوْ يَظْلِمْ نَفْسَهُ ثُمَّ يَسْتَغْفِرِ اللَّهَ يَجِدِ اللَّهَ غَفُورًا رَّحِيمًا

And whoever does a wrong or wrongs himself but then seeks forgiveness of Allah will find Allah Forgiving and Merciful.

وَمَن يَكْسِبْ خَطِيئَةً أَوْ إِثْمًا ثُمَّ يَرْمِ بِهِ بَرِيئًا فَقَدِ احْتَمَلَ بُهْتَانًا وَإِثْمًا مُّبِينًا

But whoever earns an offense or a sin and then blames it on an innocent [person] has taken upon himself a slander and manifest sin.

وَلَوْلَا فَضْلُ اللَّهِ عَلَيْكَ وَرَحْمَتُهُ لَهَمَّت طَّائِفَةٌ مِّنْهُمْ أَن يُضِلُّوكَ وَمَا يُضِلُّونَ إِلَّا أَنفُسَهُمْ ۖ وَمَا يَضُرُّونَكَ مِن شَيْءٍ ۚ وَأَنزَلَ اللَّهُ عَلَيْكَ الْكِتَابَ وَالْحِكْمَةَ وَعَلَّمَكَ مَا لَمْ تَكُن تَعْلَمُ ۚ وَكَانَ فَضْلُ اللَّهِ 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 فِي كَثِيرٍ مِّن نَّجْوَاهُمْ إِلَّا مَنْ أَمَرَ بِصَدَقَةٍ أَوْ مَعْرُوفٍ أَوْ إِصْلَاحٍ بَيْنَ النَّاسِ ۚ وَمَن يَفْعَلْ ذَٰلِكَ ابْتِغَاءَ مَرْضَاتِ اللَّهِ 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.
