Sura al-Baqara 2:140

أَمْ تَقُولُونَ إِنَّ إِبْرَٰهِـۧمَ وَإِسْمَٰعِيلَ وَإِسْحَٰقَ وَيَعْقُوبَ وَٱلْأَسْبَاطَ كَانُوا۟ هُودًا أَوْ نَصَٰرَىٰ قُلْ ءَأَنتُمْ أَعْلَمُ أَمِ ٱللَّـهُ وَمَنْ أَظْلَمُ مِمَّن كَتَمَ شَهَٰدَةً عِندَهُۥ مِنَ ٱللَّـهِ وَمَا ٱللَّـهُ بِغَٰفِلٍ عَمَّا تَعْمَلُونَ

am taqūlūna inna ibrāhīma wa-ismāʿīla wa-isḥāqa wa-yaʿqūba wa-l-asbāṭa kānū hūdan aw naṣārā qul aʾantum aʿlamu ami allāhu wa-man aẓlamu mimman katama shahādatan ʿindahu mina allāhi wa-mā allāhu bi-ghāfilin ʿammā taʿmalūna

Or do ye say that Abraham, Isma'il Isaac, Jacob and the Tribes were Jews or Christians? Say: Do ye know better than Allah? Ah! who is more unjust than those who conceal the testimony they have from Allah? but Allah is not unmindful of what ye do!

Sura al-Baqara 2:146

ٱلَّذِينَ ءَاتَيْنَٰهُمُ ٱلْكِتَٰبَ يَعْرِفُونَهُۥ كَمَا يَعْرِفُونَ أَبْنَآءَهُمْ وَإِنَّ فَرِيقًا مِّنْهُمْ لَيَكْتُمُونَ ٱلْحَقَّ وَهُمْ يَعْلَمُونَ

lladhīna ātaynāhumu l-kitāba yaʿrifūnahu ka-mā yaʿrifūna abnāʾahum wa-inna farīqan minhum la-yaktumūna l-ḥaqqa wa-hum yaʿlamūna

The people of the Book know this as they know their own sons; but some of them conceal the truth which they themselves know.

Sura al-Baqara 2:159

إِنَّ ٱلَّذِينَ يَكْتُمُونَ مَآ أَنزَلْنَا مِنَ ٱلْبَيِّنَٰتِ وَٱلْهُدَىٰ مِنۢ بَعْدِ مَا بَيَّنَّٰهُ لِلنَّاسِ فِى ٱلْكِتَٰبِ أُو۟لَٰٓئِكَ يَلْعَنُهُمُ ٱللَّـهُ وَيَلْعَنُهُمُ ٱللَّٰعِنُونَ

inna lladhīna yaktumūna mā anzalnā mina l-bayyināti wa-l-hudā min baʿdi mā bayyannāhu lil-nāsi fī l-kitābi ulāʾika yalʿanuhumu allāhu wa-yalʿanuhumu l-lāʿinūna

Those who conceal the clear (Signs) We have sent down, and the Guidance, after We have made it clear for the people in the Book,-on them shall be Allah's curse, and the curse of those entitled to curse,-

Sura al-Baqara 2:174

إِنَّ ٱلَّذِينَ يَكْتُمُونَ مَآ أَنزَلَ ٱللَّـهُ مِنَ ٱلْكِتَٰبِ وَيَشْتَرُونَ بِهِۦ ثَمَنًا قَلِيلًا أُو۟لَٰٓئِكَ مَا يَأْكُلُونَ فِى بُطُونِهِمْ إِلَّا ٱلنَّارَ وَلَا يُكَلِّمُهُمُ ٱللَّـهُ يَوْمَ ٱلْقِيَٰمَةِ وَلَا يُزَكِّيهِمْ وَلَهُمْ عَذَابٌ أَلِيمٌ

inna lladhīna yaktumūna mā anzala allāhu mina l-kitābi wa-yashtarūna bihi thamanan qalīlan ulāʾika mā yaʾkulūna fī buṭūnihim illā l-nāra wa-lā yukallimuhumu allāhu yawma l-qiyāmati wa-lā yuzakkīhim wa-lahum ʿadhābun alīmun

Those who conceal Allah's revelations in the Book, and purchase for them a miserable profit,- they swallow into themselves naught but Fire; Allah will not address them on the Day of Resurrection. Nor purify them: Grievous will be their penalty.

Sura al-Baqara 2:228

وَٱلْمُطَلَّقَٰتُ يَتَرَبَّصْنَ بِأَنفُسِهِنَّ ثَلَٰثَةَ قُرُوٓءٍ وَلَا يَحِلُّ لَهُنَّ أَن يَكْتُمْنَ مَا خَلَقَ ٱللَّـهُ فِىٓ أَرْحَامِهِنَّ إِن كُنَّ يُؤْمِنَّ بِٱللَّـهِ وَٱلْيَوْمِ ٱلْأَخِرِ وَبُعُولَتُهُنَّ أَحَقُّ بِرَدِّهِنَّ فِى ذَٰلِكَ إِنْ أَرَادُوٓا۟ إِصْلَٰحًا وَلَهُنَّ مِثْلُ ٱلَّذِى عَلَيْهِنَّ بِٱلْمَعْرُوفِ وَلِلرِّجَالِ عَلَيْهِنَّ دَرَجَةٌ وَٱللَّـهُ عَزِيزٌ حَكِيمٌ

wa-l-muṭallaqātu yatarabbaṣna bi-anfusihinna thalāthata qurūʾin wa-lā yaḥillu la-hunna an yaktumna mā khalaqa allāhu fī arḥāmihinna in kunna yuʾminna billāhi wa-l-yawmi l-akhiri wabuʿūlatuhunna aḥaqqu bi-raddihinna fī dhālika in arādū iṣlāḥan wa-lahunna mithlu alladhī ʿalayhinna bil-maʿrūfi wa-lil-rijāli ʿalayhinna darajatun wallāhu ʿazīzun ḥakīmun

Divorced women shall wait concerning themselves for three monthly periods. Nor is it lawful for them to hide what Allah Hath created in their wombs, if they have faith in Allah and the Last Day. And their husbands have the better right to take them back in that period, if they wish for reconciliation. And women shall have rights similar to the rights against them, according to what is equitable; but men have a degree (of advantage) over them. And Allah is Exalted in Power, Wise.

Sura al-Baqara 2:283

وَإِن كُنتُمْ عَلَىٰ سَفَرٍ وَلَمْ تَجِدُوا۟ كَاتِبًا فَرِهَٰنٌ مَّقْبُوضَةٌ فَإِنْ أَمِنَ بَعْضُكُم بَعْضًا فَلْيُؤَدِّ ٱلَّذِى ٱؤْتُمِنَ أَمَٰنَتَهُۥ وَلْيَتَّقِ ٱللَّـهَ رَبَّهُۥ وَلَا تَكْتُمُوا۟ ٱلشَّهَٰدَةَ وَمَن يَكْتُمْهَا فَإِنَّهُۥٓ ءَاثِمٌ قَلْبُهُۥ وَٱللَّـهُ بِمَا تَعْمَلُونَ عَلِيمٌ

wa-in kuntum ʿalā safarin wa-lam tajidū kātiban farihānun maqbūḍatun fa-in amina baʿḍukum baʿḍan fa-l-yuʾaddi alladhī iʾtumina amānatahu wa-l-yattaqi allāha rabbahu wa-lā taktumū l-shahādata wa-man yaktumhā fainnahu āthimun qalbuhu wallāhu bi-mā taʿmalūna ʿalīmun

If ye are on a journey, and cannot find a scribe, a pledge with possession (may serve the purpose). And if one of you deposits a thing on trust with another, Let the trustee (Faithfully) discharge His trust, and let him fear his Lord. Conceal not evidence; for whoever conceals it,- His heart is tainted with sin. And Allah Knoweth all that ye do.

Sura Āl-ʿImrān 3:167

وَلِيَعْلَمَ ٱلَّذِينَ نَافَقُوا۟ وَقِيلَ لَهُمْ تَعَالَوْا۟ قَٰتِلُوا۟ فِى سَبِيلِ ٱللَّـهِ أَوِ ٱدْفَعُوا۟ قَالُوا۟ لَوْ نَعْلَمُ قِتَالًا لَّٱتَّبَعْنَٰكُمْ هُمْ لِلْكُفْرِ يَوْمَئِذٍ أَقْرَبُ مِنْهُمْ لِلْإِيمَٰنِ يَقُولُونَ بِأَفْوَٰهِهِم مَّا لَيْسَ فِى قُلُوبِهِمْ وَٱللَّـهُ أَعْلَمُ بِمَا يَكْتُمُونَ

wa-li-yaʿlama lladhīna nāfaqū waqīla lahum taʿālaw qātilū fī sabīli allāhi awi adfaʿū qālū law naʿlamu qitālan llattabaʿnākum hum lil-kufri yawmaʾidhin aqrabu minhum lil-īmāni yaqūlūna biafwāhihim mā laysa fī qulūbihim wallāhu aʿlamu bi-mā yaktumūna

And the Hypocrites also. These were told: "Come, fight in the way of Allah, or (at least) drive (The foe from your city)." They said: "Had we known how to fight, we should certainly have followed you." They were that day nearer to Unbelief than to Faith, saying with their lips what was not in their hearts but Allah hath full knowledge of all they conceal.

Sura al-Nisāʾ 4:37

ٱلَّذِينَ يَبْخَلُونَ وَيَأْمُرُونَ ٱلنَّاسَ بِٱلْبُخْلِ وَيَكْتُمُونَ مَآ ءَاتَىٰهُمُ ٱللَّـهُ مِن فَضْلِهِۦ وَأَعْتَدْنَا لِلْكَٰفِرِينَ عَذَابًا مُّهِينًا

lladhīna yabkhalūna wa-yaʾmurūna l-nāsa bil-bukhli wa-yaktumūna mā ātahumu allāhu min faḍlihi wa-aʿtadnā lil-kāfirīna ʿadhāban muhīnan

(Nor) those who are niggardly or enjoin niggardliness on others, or hide the bounties which Allah hath bestowed on them; for We have prepared, for those who resist Faith, a punishment that steeps them in contempt;-

Sura al-Nisāʾ 4:42

يَوْمَئِذٍ يَوَدُّ ٱلَّذِينَ كَفَرُوا۟ وَعَصَوُا۟ ٱلرَّسُولَ لَوْ تُسَوَّىٰ بِهِمُ ٱلْأَرْضُ وَلَا يَكْتُمُونَ ٱللَّـهَ حَدِيثًا

yawmaʾidhin yawaddu lladhīna kafarū wa-ʿaṣawu l-rasūla law tusawwa bihimu l-arḍu wa-lā yaktumūna allāha ḥadīthan

On that day those who reject Faith and disobey the messenger will wish that the earth Were made one with them: But never will they hide a single fact from Allah!

Sura al-Māʾidah 5:61

وَإِذَا جَآءُوكُمْ قَالُوٓا۟ ءَامَنَّا وَقَد دَّخَلُوا۟ بِٱلْكُفْرِ وَهُمْ قَدْ خَرَجُوا۟ بِهِۦ وَٱللَّـهُ أَعْلَمُ بِمَا كَانُوا۟ يَكْتُمُونَ

wa-idhā jāʾūkum qālū āmannā waqad dakhalū bil-kufri wa-hum qad kharajū bihi wallāhu aʿlamu bi-mā kānū yaktumūna

When they come to thee, they say: "We believe": but in fact they enter with a mind against Faith, and they go out with the same but Allah knoweth fully all that they hide.

Sura al-Ghāfir 40:28

وَقَالَ رَجُلٌ مُّؤْمِنٌ مِّنْ ءَالِ فِرْعَوْنَ يَكْتُمُ إِيمَٰنَهُۥٓ أَتَقْتُلُونَ رَجُلًا أَن يَقُولَ رَبِّىَ ٱللَّـهُ وَقَدْ جَآءَكُم بِٱلْبَيِّنَٰتِ مِن رَّبِّكُمْ وَإِن يَكُ كَٰذِبًا فَعَلَيْهِ كَذِبُهُۥ وَإِن يَكُ صَادِقًا يُصِبْكُم بَعْضُ ٱلَّذِى يَعِدُكُمْ إِنَّ ٱللَّـهَ لَا يَهْدِى مَنْ هُوَ مُسْرِفٌ كَذَّابٌ

wa-qāla rajulun muʾminun min āli firʿawna yaktumu īmānahu ataqtulūna rajulan an yaqūla rabbiya allāhu wa-qad jāʾakum bil-bayyināti min rabbikum wa-in yaku kādhiban faʿalayhi kadhibuhu wa-in yaku ṣādiqan yuṣibkum baʿḍu alladhī yaʿidukum inna allāha lā yahdī man huwa musrifun kadhdhābun

A believer, a man from among the people of Pharaoh, who had concealed his faith, said: "Will ye slay a man because he says, 'My Lord is Allah'?- when he has indeed come to you with Clear (Signs) from your Lord? and if he be a liar, on him is (the sin of) his lie: but, if he is telling the Truth, then will fall on you something of the (calamity) of which he warns you: Truly Allah guides not one who transgresses and lies!
