Al-Mujadila 58:6

وَالَّذِينَ يُظَاهِرُونَ مِن نِّسَائِهِمْ ثُمَّ يَعُودُونَ لِمَا قَالُوا فَتَحْرِيرُ رَقَبَةٍ مِّن قَبْلِ أَن يَتَمَاسَّا ۚ ذَٰلِكُمْ تُوعَظُونَ بِهِ ۚ وَاللَّهُ بِمَا تَعْمَلُونَ خَبِيرٌ

And those who pronounce thihar from their wives and then [wish to] go back on what they said - then [there must be] the freeing of a slave before they touch one another. That is what you are admonished thereby; and Allah is Acquainted with what you do.

فَمَن لَّمْ يَجِدْ فَصِيَامُ شَهْرَيْنِ مُتَتَابِعَيْنِ مِن قَبْلِ أَن يَتَمَاسَّا ۖ فَمَن لَّمْ يَسْتَطِعْ فَإِطْعَامُ سِتِّينَ مِسْكِينًا ۚ ذَٰلِكَ لِتُؤْمِنُوا بِاللَّهِ وَرَسُولِهِ ۚ وَتِلْكَ حُدُودُ اللَّهِ ۗ وَلِلْكَافِرِينَ عَذَابٌ أَلِيمٌ

And he who does not find [a slave] - then a fast for two months consecutively before they touch one another; and he who is unable - then the feeding of sixty poor persons. That is for you to believe [completely] in Allah and His Messenger; and those are the limits [set by] Allah. And for the disbelievers is a painful punishment.

إِنَّ الَّذِينَ يُحَادُّونَ اللَّهَ وَرَسُولَهُ كُبِتُوا كَمَا كُبِتَ الَّذِينَ مِن قَبْلِهِمْ ۚ وَقَدْ أَنزَلْنَا آيَاتٍ بَيِّنَاتٍ ۚ وَلِلْكَافِرِينَ عَذَابٌ مُّهِينٌ

Indeed, those who oppose Allah and His Messenger are abased as those before them were abased. And We have certainly sent down verses of clear evidence. And for the disbelievers is a humiliating punishment.

أَلَمْ تَرَ أَنَّ اللَّهَ يَعْلَمُ مَا فِي السَّمَاوَاتِ وَمَا فِي الْأَرْضِ ۖ مَا يَكُونُ مِن نَّجْوَىٰ ثَلَاثَةٍ إِلَّا هُوَ رَابِعُهُمْ وَلَا خَمْسَةٍ إِلَّا هُوَ سَادِسُهُمْ وَلَا أَدْنَىٰ مِن ذَٰلِكَ وَلَا أَكْثَرَ إِلَّا هُوَ مَعَهُمْ أَيْنَ مَا كَانُوا ۖ ثُمَّ يُنَبِّئُهُم بِمَا عَمِلُوا يَوْمَ الْقِيَامَةِ ۚ إِنَّ اللَّهَ بِكُلِّ شَيْءٍ عَلِيمٌ

Have you not considered that Allah knows what is in the heavens and what is on the earth? There is in no private conversation three but that He is the fourth of them, nor are there five but that He is the sixth of them - and no less than that and no more except that He is with them [in knowledge] wherever they are. Then He will inform them of what they did, on the Day of Resurrection. Indeed Allah is, of all things, Knowing.

أَلَمْ تَرَ إِلَى الَّذِينَ نُهُوا عَنِ النَّجْوَىٰ ثُمَّ يَعُودُونَ لِمَا نُهُوا عَنْهُ وَيَتَنَاجَوْنَ بِالْإِثْمِ وَالْعُدْوَانِ وَمَعْصِيَتِ الرَّسُولِ وَإِذَا جَاءُوكَ حَيَّوْكَ بِمَا لَمْ يُحَيِّكَ بِهِ اللَّهُ وَيَقُولُونَ فِي أَنفُسِهِمْ لَوْلَا يُعَذِّبُنَا اللَّهُ بِمَا نَقُولُ ۚ حَسْبُهُمْ جَهَنَّمُ يَصْلَوْنَهَا ۖ فَبِئْسَ الْمَصِيرُ

Have you not considered those who were forbidden from private conversation, then they return to that which they were forbidden and converse among themselves about sin and aggression and disobedience to the Messenger? And when they come to you, they greet you with that [word] by which Allah does not greet you and say among themselves, "Why does Allah not punish us for what we say?" Sufficient for them is Hell, which they will [enter to] burn, and wretched is the destination.

يَا أَيُّهَا الَّذِينَ آمَنُوا إِذَا تَنَاجَيْتُمْ فَلَا تَتَنَاجَوْا بِالْإِثْمِ وَالْعُدْوَانِ وَمَعْصِيَتِ الرَّسُولِ وَتَنَاجَوْا بِالْبِرِّ وَالتَّقْوَىٰ ۖ وَاتَّقُوا اللَّهَ الَّذِي إِلَيْهِ تُحْشَرُونَ

O you who have believed, when you converse privately, do not converse about sin and aggression and disobedience to the Messenger but converse about righteousness and piety. And fear Allah, to whom you will be gathered.
