The Quran root ك ب ر k-b-r

وَإِذْ قُلْنَا لِلْمَلَائِكَةِ اسْجُدُوا لِآدَمَ فَسَجَدُوا إِلَّا إِبْلِيسَ أَبَىٰ وَاسْتَكْبَرَ وَكَانَ مِنَ الْكَافِرِينَ ٣٤

وَاسْتَكْبَرَ wa-is'takbara · and was arrogant

And [mention] when We said to the angels, "Prostrate before Adam"; so they prostrated, except for Iblees. He refused and was arrogant and became of the disbelievers. (Surah Al-Baqarah, 2:34)

وَلَقَدْ آتَيْنَا مُوسَى الْكِتَابَ وَقَفَّيْنَا مِن بَعْدِهِ بِالرُّسُلِ وَآتَيْنَا عِيسَى ابْنَ مَرْيَمَ الْبَيِّنَاتِ وَأَيَّدْنَاهُ بِرُوحِ الْقُدُسِ أَفَكُلَّمَا جَاءَكُمْ رَسُولٌ بِمَا لَا تَهْوَىٰ أَنفُسُكُمُ اسْتَكْبَرْتُمْ فَفَرِيقًا كَذَّبْتُمْ وَفَرِيقًا تَقْتُلُونَ ٨٧

اسْتَكْبَرْتُمْ is'takbartum · you acted arrogantly

And We did certainly give Moses the Scripture [i.e., the Torah] and followed up after him with messengers. And We gave Jesus, the son of Mary, clear proofs and supported him with the Pure Spirit [i.e., the angel Gabriel]. But is it [not] that every time a messenger came to you, [O Children of Israel], with what your souls did not desire, you were arrogant? And a party [of messengers] you denied and another party you killed. (Surah Al-Baqarah, 2:87)

يَسْأَلُونَكَ عَنِ الشَّهْرِ الْحَرَامِ قِتَالٍ فِيهِ قُلْ قِتَالٌ فِيهِ كَبِيرٌ وَصَدٌّ عَن سَبِيلِ اللَّهِ وَكُفْرٌ بِهِ وَالْمَسْجِدِ الْحَرَامِ وَإِخْرَاجُ أَهْلِهِ مِنْهُ أَكْبَرُ عِندَ اللَّهِ وَالْفِتْنَةُ أَكْبَرُ مِنَ الْقَتْلِ وَلَا يَزَالُونَ يُقَاتِلُونَكُمْ حَتَّىٰ يَرُدُّوكُمْ عَن دِينِكُمْ إِنِ اسْتَطَاعُوا وَمَن يَرْتَدِدْ مِنكُمْ عَن دِينِهِ فَيَمُتْ وَهُوَ كَافِرٌ فَأُولَٰئِكَ حَبِطَتْ أَعْمَالُهُمْ فِي الدُّنْيَا وَالْآخِرَةِ وَأُولَٰئِكَ أَصْحَابُ النَّارِ هُمْ فِيهَا خَالِدُونَ ٢١٧

كَبِيرٌ kabīrun · (is) a great (sin)

They ask you about the sacred month - about fighting therein. Say, "Fighting therein is great [sin], but averting [people] from the way of Allāh and disbelief in Him and [preventing access to] al-Masjid al-Ḥarām and the expulsion of its people therefrom are greater [evil] in the sight of Allāh. And fitnah is greater than killing." And they will continue to fight you until they turn you back from your religion if they are able. And whoever of you reverts from his religion [to disbelief] and dies while he is a disbeliever - for those, their deeds have become worthless in this world and the Hereafter, and those are the companions of the Fire; they will abide therein eternally. (Surah Al-Baqarah, 2:217)

يَسْأَلُونَكَ عَنِ الْخَمْرِ وَالْمَيْسِرِ قُلْ فِيهِمَا إِثْمٌ كَبِيرٌ وَمَنَافِعُ لِلنَّاسِ وَإِثْمُهُمَا أَكْبَرُ مِن نَّفْعِهِمَا وَيَسْأَلُونَكَ مَاذَا يُنفِقُونَ قُلِ الْعَفْوَ كَذَٰلِكَ يُبَيِّنُ اللَّهُ لَكُمُ الْآيَاتِ لَعَلَّكُمْ تَتَفَكَّرُونَ ٢١٩

أَكْبَرُ akbaru · (is) greater

They ask you about wine and gambling. Say, "In them is great sin and [yet, some] benefit for people. But their sin is greater than their benefit." And they ask you what they should spend. Say, "The excess [beyond needs]." Thus Allāh makes clear to you the verses [of revelation] that you might give thought (Surah Al-Baqarah, 2:219)

وَابْتَلُوا الْيَتَامَىٰ حَتَّىٰ إِذَا بَلَغُوا النِّكَاحَ فَإِنْ آنَسْتُم مِّنْهُمْ رُشْدًا فَادْفَعُوا إِلَيْهِمْ أَمْوَالَهُمْ وَلَا تَأْكُلُوهَا إِسْرَافًا وَبِدَارًا أَن يَكْبَرُوا وَمَن كَانَ غَنِيًّا فَلْيَسْتَعْفِفْ وَمَن كَانَ فَقِيرًا فَلْيَأْكُلْ بِالْمَعْرُوفِ فَإِذَا دَفَعْتُمْ إِلَيْهِمْ أَمْوَالَهُمْ فَأَشْهِدُوا عَلَيْهِمْ وَكَفَىٰ بِاللَّهِ حَسِيبًا ٦

يَكْبَرُوا yakbarū · they will grow up

And test the orphans [in their abilities] until they reach marriageable age. Then if you perceive in them sound judgement, release their property to them. And do not consume it excessively and quickly, [anticipating] that they will grow up. And whoever, [when acting as guardian], is self-sufficient should refrain [from taking a fee]; and whoever is poor - let him take according to what is acceptable. Then when you release their property to them, bring witnesses upon them. And sufficient is Allāh as Accountant. (Surah An-Nisa, 4:6)

وَاسْتَعِينُوا بِالصَّبْرِ وَالصَّلَاةِ وَإِنَّهَا لَكَبِيرَةٌ إِلَّا عَلَى الْخَاشِعِينَ ٤٥

لَكَبِيرَةٌ lakabīratun · (is) surely difficult

And seek help through patience and prayer; and indeed, it is difficult except for the humbly submissive [to Allāh] (Surah Al-Baqarah, 2:45)
