False oaths (Perjury)

إِنَّ ٱلَّذِينَ يَشْتَرُونَ بِعَهْدِ ٱللَّهِ وَأَيْمَٰنِهِمْ ثَمَنًۭا قَلِيلًا أُو۟لَٰٓئِكَ لَا خَلَٰقَ لَهُمْ فِى ٱلْءَاخِرَةِ وَلَا يُكَلِّمُهُمُ ٱللَّهُ وَلَا يَنظُرُ إِلَيْهِمْ يَوْمَ ٱلْقِيَٰمَةِ وَلَا يُزَكِّيهِمْ وَلَهُمْ عَذَابٌ أَلِيمٌۭ

As for those who sell the faith they owe to Allah and their own plighted word for a small price, they shall have no portion in the Hereafter: Nor will Allah (Deign to) speak to them or look at them on the Day of Judgment, nor will He cleans them (of sin): They shall have a grievous penalty.

وَأَقْسَمُوا۟ بِٱللَّهِ جَهْدَ أَيْمَٰنِهِمْ لَئِن جَآءَتْهُمْ ءَايَةٌۭ لَّيُؤْمِنُنَّ بِهَا ۚ قُلْ إِنَّمَا ٱلْءَايَٰتُ عِندَ ٱللَّهِ ۖ وَمَا يُشْعِرُكُمْ أَنَّهَآ إِذَا جَآءَتْ لَا يُؤْمِنُونَ

They swear their strongest oaths by Allah, that if a (special) sign came to them, by it they would believe. Say: "Certainly (all) signs are in the power of Allah: but what will make you (Muslims) realise that (even) if (special) signs came, they will not believe."?

لَوْ كَانَ عَرَضًۭا قَرِيبًۭا وَسَفَرًۭا قَاصِدًۭا لَّٱتَّبَعُوكَ وَلَٰكِنۢ بَعُدَتْ عَلَيْهِمُ ٱلشُّقَّةُ ۚ وَسَيَحْلِفُونَ بِٱللَّهِ لَوِ ٱسْتَطَعْنَا لَخَرَجْنَا مَعَكُمْ يُهْلِكُونَ أَنفُسَهُمْ وَٱللَّهُ يَعْلَمُ إِنَّهُمْ لَكَٰذِبُونَ

If there had been immediate gain (in sight), and the journey easy, they would (all) without doubt have followed thee, but the distance was long, (and weighed) on them. They would indeed swear by Allah, "If we only could, we should certainly have come out with you": They would destroy their own souls; for Allah doth know that they are certainly lying.

وَٱلَّذِينَ ٱتَّخَذُوا۟ مَسْجِدًۭا ضِرَارًۭا وَكُفْرًۭا وَتَفْرِيقًۢا بَيْنَ ٱلْمُؤْمِنِينَ وَإِرْصَادًۭا لِّمَنْ حَارَبَ ٱللَّهَ وَرَسُولَهُۥ مِن قَبْلُ ۚ وَلَيَحْلِفُنَّ إِنْ أَرَدْنَآ إِلَّا ٱلْحُسْنَىٰ ۖ وَٱللَّهُ يَشْهَدُ إِنَّهُمْ لَكَٰذِبُونَ

And there are those who put up a mosque by way of mischief and infidelity - to disunite the Believers - and in preparation for one who warred against Allah and His Messenger aforetime. They will indeed swear that their intention is nothing but good; But Allah doth declare that they are certainly liars.

۞ أَلَمْ تَرَ إِلَى ٱلَّذِينَ تَوَلَّوْا۟ قَوْمًا غَضِبَ ٱللَّهُ عَلَيْهِم مَّا هُم مِّنكُمْ وَلَا مِنْهُمْ وَيَحْلِفُونَ عَلَى ٱلْكَذِبِ وَهُمْ يَعْلَمُونَ

Turnest thou not thy attention to those who turn (in friendship) to such as have the Wrath of Allah upon them? They are neither of you nor of them, and they swear to falsehood knowingly.
