وَآمِنُوا بِمَا أَنزَلْتُ مُصَدِّقًا لِّمَا مَعَكُمْ وَلَا تَكُونُوا أَوَّلَ كَافِرٍ بِهِ وَلَا تَشْتَرُوا بِآيَاتِي ثَمَنًا قَلِيلًا وَإِيَّايَ فَاتَّقُونِ ٤١

ثَمَنًا thamanan · a price

And believe in what I have sent down confirming that which is [already] with you, and be not the first to disbelieve in it. And do not exchange My signs for a small price, and fear [only] Me. (Surah Al-Baqarah, 2:41)

فَوَيْلٌ لِّلَّذِينَ يَكْتُبُونَ الْكِتَابَ بِأَيْدِيهِمْ ثُمَّ يَقُولُونَ هَٰذَا مِنْ عِندِ اللَّهِ لِيَشْتَرُوا بِهِ ثَمَنًا قَلِيلًا فَوَيْلٌ لَّهُم مِّمَّا كَتَبَتْ أَيْدِيهِمْ وَوَيْلٌ لَّهُم مِّمَّا يَكْسِبُونَ ٧٩

ثَمَنًا thamanan · (for) a price

So woe to those who write the "scripture" with their own hands, then say, "This is from Allāh," in order to exchange it for a small price. Woe to them for what their hands have written and woe to them for what they earn. (Surah Al-Baqarah, 2:79)

ثَمَانِيَةَ أَزْوَاجٍ مِّنَ الضَّأْنِ اثْنَيْنِ وَمِنَ الْمَعْزِ اثْنَيْنِ قُلْ آلذَّكَرَيْنِ حَرَّمَ أَمِ الْأُنثَيَيْنِ أَمَّا اشْتَمَلَتْ عَلَيْهِ أَرْحَامُ الْأُنثَيَيْنِ نَبِّئُونِي بِعِلْمٍ إِن كُنتُمْ صَادِقِينَ ١٤٣

ثَمَانِيَةَ thamāniyata · Eight

[They are] eight mates - of the sheep, two and of the goats, two. Say, "Is it the two males He has forbidden or the two females or that which the wombs of the two females contain? Inform me with knowledge, if you should be truthful." (Surah Al-An'am, 6:143)

وَلَكُمْ نِصْفُ مَا تَرَكَ أَزْوَاجُكُمْ إِن لَّمْ يَكُن لَّهُنَّ وَلَدٌ فَإِن كَانَ لَهُنَّ وَلَدٌ فَلَكُمُ الرُّبُعُ مِمَّا تَرَكْنَ مِن بَعْدِ وَصِيَّةٍ يُوصِينَ بِهَا أَوْ دَيْنٍ وَلَهُنَّ الرُّبُعُ مِمَّا تَرَكْتُمْ إِن لَّمْ يَكُن لَّكُمْ وَلَدٌ فَإِن كَانَ لَكُمْ وَلَدٌ فَلَهُنَّ الثُّمُنُ مِمَّا تَرَكْتُم مِّن بَعْدِ وَصِيَّةٍ تُوصُونَ بِهَا أَوْ دَيْنٍ وَإِن كَانَ رَجُلٌ يُورَثُ كَلَالَةً أَوِ امْرَأَةٌ وَلَهُ أَخٌ أَوْ أُخْتٌ فَلِكُلِّ وَاحِدٍ مِّنْهُمَا السُّدُسُ فَإِن كَانُوا أَكْثَرَ مِن ذَٰلِكَ فَهُمْ شُرَكَاءُ فِي الثُّلُثِ مِن بَعْدِ وَصِيَّةٍ يُوصَىٰ بِهَا أَوْ دَيْنٍ غَيْرَ مُضَارٍّ وَصِيَّةً مِّنَ اللَّهِ وَاللَّهُ عَلِيمٌ حَلِيمٌ ١٢

الثُّمُنُ l-thumunu · (is) the eighth

And for you is half of what your wives leave if they have no child. But if they have a child, for you is one fourth of what they leave, after any bequest they [may have] made or debt. And for them [i.e., the wives] is one fourth if you leave no child. But if you leave a child, then for them is an eighth of what you leave, after any bequest you [may have] made or debt. And if a man or woman leaves neither ascendants nor descendants but has a brother or a sister, then for each one of them is a sixth. But if they are more than two, they share a third, after any bequest which was made or debt, as long as there is no detriment [caused]. [This is] an ordinance from Allāh, and Allāh is Knowing and Forbearing. (Surah An-Nisa, 4:12)

سَيَقُولُونَ ثَلَاثَةٌ رَّابِعُهُمْ كَلْبُهُمْ وَيَقُولُونَ خَمْسَةٌ سَادِسُهُمْ كَلْبُهُمْ رَجْمًا بِالْغَيْبِ وَيَقُولُونَ سَبْعَةٌ وَثَامِنُهُمْ كَلْبُهُمْ قُل رَّبِّي أَعْلَمُ بِعِدَّتِهِم مَّا يَعْلَمُهُمْ إِلَّا قَلِيلٌ فَلَا تُمَارِ فِيهِمْ إِلَّا مِرَاءً ظَاهِرًا وَلَا تَسْتَفْتِ فِيهِم مِّنْهُمْ أَحَدًا ٢٢

وَثَامِنُهُمْ wathāminuhum · and the eight of them

They [i.e., people] will say there were three, the fourth of them being their dog; and they will say there were five, the sixth of them being their dog - guessing at the unseen; and they will say there were seven, and the eighth of them was their dog. Say, [O Muḥammad], "My Lord is most knowing of their number. None knows them except a few. So do not argue about them except with an obvious argument and do not inquire about them among [the speculators] from anyone." (Surah Al-Kahf, 18:22)

وَالَّذِينَ يَرْمُونَ الْمُحْصَنَاتِ ثُمَّ لَمْ يَأْتُوا بِأَرْبَعَةِ شُهَدَاءَ فَاجْلِدُوهُمْ ثَمَانِينَ جَلْدَةً وَلَا تَقْبَلُوا لَهُمْ شَهَادَةً أَبَدًا وَأُولَٰئِكَ هُمُ الْفَاسِقُونَ ٤

ثَمَانِينَ thamānīna · (with) eighty

And those who accuse chaste women and then do not produce four witnesses - lash them with eighty lashes and do not accept from them testimony ever after. And those are the defiantly disobedient, (Surah An-Nur, 24:4)
