تَخُونُوا takhūnū · betray

O you who have believed, do not betray Allāh and the Messenger or betray your trusts while you know [the consequence]. (Surah Al-Anfal, 8:27)

وَإِن يُرِيدُوا خِيَانَتَكَ فَقَدْ خَانُوا اللَّهَ مِن قَبْلُ فَأَمْكَنَ مِنْهُمْ وَاللَّهُ عَلِيمٌ حَكِيمٌ ٧١

خَانُوا khānū · they have betrayed

But if they intend to betray you - then they have already betrayed Allāh before, and He empowered [you] over them. And Allāh is Knowing and Wise. (Surah Al-Anfal, 8:71)

إِنَّا أَنزَلْنَا إِلَيْكَ الْكِتَابَ بِالْحَقِّ لِتَحْكُمَ بَيْنَ النَّاسِ بِمَا أَرَاكَ اللَّهُ وَلَا تَكُن لِّلْخَائِنِينَ خَصِيمًا ١٠٥

لِّلْخَائِنِينَ lil'khāinīna · for the deceitful

Indeed, We have revealed to you, [O Muḥammad], the Book in truth so you may judge between the people by that which Allāh has shown you. And do not be for the deceitful an advocate. (Surah An-Nisa, 4:105)

أُحِلَّ لَكُمْ لَيْلَةَ الصِّيَامِ الرَّفَثُ إِلَىٰ نِسَائِكُمْ هُنَّ لِبَاسٌ لَّكُمْ وَأَنتُمْ لِبَاسٌ لَّهُنَّ عَلِمَ اللَّهُ أَنَّكُمْ كُنتُمْ تَخْتَانُونَ أَنفُسَكُمْ فَتَابَ عَلَيْكُمْ وَعَفَا عَنكُمْ فَالْآنَ بَاشِرُوهُنَّ وَابْتَغُوا مَا كَتَبَ اللَّهُ لَكُمْ وَكُلُوا وَاشْرَبُوا حَتَّىٰ يَتَبَيَّنَ لَكُمُ الْخَيْطُ الْأَبْيَضُ مِنَ الْخَيْطِ الْأَسْوَدِ مِنَ الْفَجْرِ ثُمَّ أَتِمُّوا الصِّيَامَ إِلَى اللَّيْلِ وَلَا تُبَاشِرُوهُنَّ وَأَنتُمْ عَاكِفُونَ فِي الْمَسَاجِدِ تِلْكَ حُدُودُ اللَّهِ فَلَا تَقْرَبُوهَا كَذَٰلِكَ يُبَيِّنُ اللَّهُ آيَاتِهِ لِلنَّاسِ لَعَلَّهُمْ يَتَّقُونَ ١٨٧

تَخْتَانُونَ takhtānūna · deceive

It has been made permissible for you the night preceding fasting to go to your wives [for sexual relations]. They are a clothing for you and you are a clothing for them. Allāh knows that you used to deceive yourselves, so He accepted your repentance and forgave you. So now, have relations with them and seek that which Allāh has decreed for you [i.e., offspring]. And eat and drink until the white thread of dawn becomes distinct to you from the black thread [of night]. Then complete the fast until the night [i.e., sunset]. And do not have relations with them as long as you are staying for worship in the mosques. These are the limits [set by] Allāh, so do not approach them. Thus does Allāh make clear His verses [i.e., ordinances] to the people that they may become righteous. (Surah Al-Baqarah, 2:187)

وَلَا تُجَادِلْ عَنِ الَّذِينَ يَخْتَانُونَ أَنفُسَهُمْ إِنَّ اللَّهَ لَا يُحِبُّ مَن كَانَ خَوَّانًا أَثِيمًا ١٠٧

خَوَّانًا khawwānan · treacherous

And do not argue on behalf of those who deceive themselves. Indeed, Allāh loves not one who is a habitually sinful deceiver. (Surah An-Nisa, 4:107)

فَبِمَا نَقْضِهِم مِّيثَاقَهُمْ لَعَنَّاهُمْ وَجَعَلْنَا قُلُوبَهُمْ قَاسِيَةً يُحَرِّفُونَ الْكَلِمَ عَن مَّوَاضِعِهِ وَنَسُوا حَظًّا مِّمَّا ذُكِّرُوا بِهِ وَلَا تَزَالُ تَطَّلِعُ عَلَىٰ خَائِنَةٍ مِّنْهُمْ إِلَّا قَلِيلًا مِّنْهُمْ فَاعْفُ عَنْهُمْ وَاصْفَحْ إِنَّ اللَّهَ يُحِبُّ الْمُحْسِنِينَ ١٣

خَائِنَةٍ khāinatin · treachery

So for their breaking of the covenant We cursed them and made their hearts hardened. They distort words from their [proper] places [i.e., usages] and have forgotten a portion of that of which they were reminded. And you will still observe deceit among them, except a few of them. But pardon them and overlook [their misdeeds]. Indeed, Allāh loves the doers of good. (Surah Al-Ma'idah, 5:13)
