The Quran root ق ل ب q-l-b

خَتَمَ اللَّهُ عَلَىٰ قُلُوبِهِمْ وَعَلَىٰ سَمْعِهِمْ وَعَلَىٰ أَبْصَارِهِمْ غِشَاوَةٌ وَلَهُمْ عَذَابٌ عَظِيمٌ ٧

قُلُوبِهِمْ qulūbihim · their hearts

Allāh has set a seal upon their hearts and upon their hearing, and over their vision is a veil. And for them is a great punishment. (Surah Al-Baqarah, 2:7)

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

قُلُوبِهِم qulūbihim · their hearts

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)

وَكَذَٰلِكَ جَعَلْنَاكُمْ أُمَّةً وَسَطًا لِّتَكُونُوا شُهَدَاءَ عَلَى النَّاسِ وَيَكُونَ الرَّسُولُ عَلَيْكُمْ شَهِيدًا وَمَا جَعَلْنَا الْقِبْلَةَ الَّتِي كُنتَ عَلَيْهَا إِلَّا لِنَعْلَمَ مَن يَتَّبِعُ الرَّسُولَ مِمَّن يَنقَلِبُ عَلَىٰ عَقِبَيْهِ وَإِن كَانَتْ لَكَبِيرَةً إِلَّا عَلَى الَّذِينَ هَدَى اللَّهُ وَمَا كَانَ اللَّهُ لِيُضِيعَ إِيمَانَكُمْ إِنَّ اللَّهَ بِالنَّاسِ لَرَءُوفٌ رَّحِيمٌ ١٤٣

يَنقَلِبُ yanqalibu · turns back

And thus We have made you a median [i.e., just] community that you will be witnesses over the people and the Messenger will be a witness over you. And We did not make the qiblah which you used to face except that We might make evident who would follow the Messenger from who would turn back on his heels. And indeed, it is difficult except for those whom Allāh has guided. And never would Allāh have caused you to lose your faith [i.e., your previous prayers]. Indeed Allāh is, to the people, Kind and Merciful. (Surah Al-Baqarah, 2:143)

وَنُقَلِّبُ أَفْئِدَتَهُمْ وَأَبْصَارَهُمْ كَمَا لَمْ يُؤْمِنُوا بِهِ أَوَّلَ مَرَّةٍ وَنَذَرُهُمْ فِي طُغْيَانِهِمْ يَعْمَهُونَ ١١٠

وَنُقَلِّبُ wanuqallibu · And We will turn

And We will turn away their hearts and their eyes just as they refused to believe in it [i.e., the revelation] the first time. And We will leave them in their transgression, wandering blindly. (Surah Al-An'am, 6:110)

قَدْ نَرَىٰ تَقَلُّبَ وَجْهِكَ فِي السَّمَاءِ فَلَنُوَلِّيَنَّكَ قِبْلَةً تَرْضَاهَا فَوَلِّ وَجْهَكَ شَطْرَ الْمَسْجِدِ الْحَرَامِ وَحَيْثُ مَا كُنتُمْ فَوَلُّوا وُجُوهَكُمْ شَطْرَهُ وَإِنَّ الَّذِينَ أُوتُوا الْكِتَابَ لَيَعْلَمُونَ أَنَّهُ الْحَقُّ مِن رَّبِّهِمْ وَمَا اللَّهُ بِغَافِلٍ عَمَّا يَعْمَلُونَ ١٤٤

تَقَلُّبَ taqalluba · (the) turning

We have certainly seen the turning of your face, [O Muḥammad], toward the heaven, and We will surely turn you to a qiblah with which you will be pleased. So turn your face [i.e., yourself] toward al-Masjid al-Ḥarām. And wherever you [believers] are, turn your faces [i.e., yourselves] toward it [in prayer]. Indeed, those who have been given the Scripture [i.e., the Jews and the Christians] well know that it is the truth from their Lord. And Allāh is not unaware of what they do. (Surah Al-Baqarah, 2:144)

قَالُوا إِنَّا إِلَىٰ رَبِّنَا مُنقَلِبُونَ ١٢٥

مُنقَلِبُونَ munqalibūna · (will) return

They said, "Indeed, to our Lord we will return. (Surah Al-A'raf, 7:125)
