فِي قُلُوبِهِم مَّرَضٌ فَزَادَهُمُ اللَّهُ مَرَضًا وَلَهُمْ عَذَابٌ أَلِيمٌ بِمَا كَانُوا يَكْذِبُونَ ١٠

كَانُوا kānū · they used to

In their hearts is disease, so Allāh has increased their disease; and for them is a painful punishment because they [habitually] used to lie. (Surah Al-Baqarah, 2:10)

أُولَٰئِكَ الَّذِينَ اشْتَرَوُا الضَّلَالَةَ بِالْهُدَىٰ فَمَا رَبِحَت تِّجَارَتُهُمْ وَمَا كَانُوا مُهْتَدِينَ ١٦

كَانُوا kānū · were they

Those are the ones who have purchased error [in exchange] for guidance, so their transaction has brought no profit, nor were they guided. (Surah Al-Baqarah, 2:16)

وَإِنْ أَرَدتُّمُ اسْتِبْدَالَ زَوْجٍ مَّكَانَ زَوْجٍ وَآتَيْتُمْ إِحْدَاهُنَّ قِنطَارًا فَلَا تَأْخُذُوا مِنْهُ شَيْئًا أَتَأْخُذُونَهُ بُهْتَانًا وَإِثْمًا مُّبِينًا ٢٠

مَّكَانَ makāna · (in) place

But if you want to replace one wife with another and you have given one of them a great amount [in gifts], do not take [back] from it anything. Would you take it in injustice and manifest sin? (Surah An-Nisa, 4:20)

قُلْ يَا قَوْمِ اعْمَلُوا عَلَىٰ مَكَانَتِكُمْ إِنِّي عَامِلٌ فَسَوْفَ تَعْلَمُونَ مَن تَكُونُ لَهُ عَاقِبَةُ الدَّارِ إِنَّهُ لَا يُفْلِحُ الظَّالِمُونَ ١٣٥

مَكَانَتِكُمْ makānatikum · your position

Say, "O my people, work according to your position; [for] indeed, I am working. And you are going to know who will have succession in the home. Indeed, the wrongdoers will not succeed." (Surah Al-An'am, 6:135)
