ثُمَّ قَسَتْ قُلُوبُكُم مِّنۢ بَعْدِ ذَٰلِكَ فَهِىَ كَٱلْحِجَارَةِ أَوْ أَشَدُّ قَسْوَةً ۚ وَإِنَّ مِنَ ٱلْحِجَارَةِ لَمَا يَتَفَجَّرُ مِنْهُ ٱلْأَنْهَـٰرُ ۚ وَإِنَّ مِنْهَا لَمَا يَشَّقَّقُ فَيَخْرُجُ مِنْهُ ٱلْمَآءُ ۚ وَإِنَّ مِنْهَا لَمَا يَهْبِطُ مِنْ خَشْيَةِ ٱللَّهِ ۗ وَمَا ٱللَّهُ بِغَـٰفِلٍ عَمَّا تَعْمَلُونَ

Then your hearts became hardened after that, being like stones or even harder. For indeed, there are stones from which rivers burst forth, and there are some of them that split open and water comes out, and there are some of them that fall down for fear of Allāh. And Allāh is not unaware of what you do.

Al-Baqarah 74

وَمِنَ ٱلنَّاسِ مَن يَتَّخِذُ مِن دُونِ ٱللَّهِ أَندَادًا يُحِبُّونَهُمْ كَحُبِّ ٱللَّهِ ۖ وَٱلَّذِينَ ءَامَنُوٓا۟ أَشَدُّ حُبًّا لِّلَّهِ ۗ وَلَوْ يَرَى ٱلَّذِينَ ظَلَمُوٓا۟ إِذْ يَرَوْنَ ٱلْعَذَابَ أَنَّ ٱلْقُوَّةَ لِلَّهِ جَمِيعًا وَأَنَّ ٱللَّهَ شَدِيدُ ٱلْعَذَابِ

And [yet], among the people are those who take other than Allāh as equals [to Him]. They love them as they [should] love Allāh. But those who believe are stronger in love for Allāh. And if only they who have wronged would consider [that] when they see the punishment, [they will be certain] that all power belongs to Allāh and that Allāh is severe in punishment.

Al-Baqarah 165

۞ تِلْكَ ٱلرُّسُلُ فَضَّلْنَا بَعْضَهُمْ عَلَىٰ بَعْضٍ ۘ مِّنْهُم مَّن كَلَّمَ ٱللَّهُ ۖ وَرَفَعَ بَعْضَهُمْ دَرَجَـٰتٍ ۚ وَءَاتَيْنَا عِيسَى ٱبْنَ مَرْيَمَ ٱلْبَيِّنَـٰتِ وَأَيَّدْنَـٰهُ بِرُوحِ ٱلْقُدُسِ ۗ وَلَوْ شَآءَ ٱللَّهُ مَا ٱقْتَتَلَ ٱلَّذِينَ مِنۢ بَعْدِهِم مِّنۢ بَعْدِ مَا جَآءَتْهُمُ ٱلْبَيِّنَـٰتُ وَلَـٰكِنِ ٱخْتَلَفُوا۟ فَمِنْهُم مَّنْ ءَامَنَ وَمِنْهُم مَّن كَفَرَ ۚ وَلَوْ شَآءَ ٱللَّهُ مَا ٱقْتَتَلُوا۟ وَلَـٰكِنَّ ٱللَّهَ يَفْعَلُ مَا يُرِيدُ

Those messengers - some of them We caused to exceed others. Among them were those to whom Allāh spoke, and He raised some of them in degree. And We gave Jesus, the son of Mary, clear proofs, and We supported him with the Pure Spirit [i.e., Gabriel]. If Allāh had willed, those [generations] succeeding them would not have fought each other after the clear proofs had come to them. But they differed, and some of them believed and some of them disbelieved. And if Allāh had willed, they would not have fought each other, but Allāh does what He intends.

Al-Baqarah 253

وَمَآ أَصَـٰبَكُمْ يَوْمَ ٱلْتَقَى ٱلْجَمْعَانِ فَبِإِذْنِ ٱللَّهِ وَلِيَعْلَمَ ٱلْمُؤْمِنِينَ

And what struck you on the day the two armies met [at Uḥud] was by permission of Allāh that He might make evident the [true] believers

Ali 'Imran 166

ثُمَّ أَنزَلَ عَلَيْكُم مِّنۢ بَعْدِ ٱلْغَمِّ أَمَنَةً نُّعَاسًا يَغْشَىٰ طَآئِفَةً مِّنكُمْ ۖ وَطَآئِفَةٌ قَدْ أَهَمَّتْهُمْ أَنفُسُهُمْ يَظُنُّونَ بِٱللَّهِ غَيْرَ ٱلْحَقِّ ظَنَّ ٱلْجَـٰهِلِيَّةِ ۖ يَقُولُونَ هَل لَّنَا مِنَ ٱلْأَمْرِ مِن شَىْءٍ ۗ قُلْ إِنَّ ٱلْأَمْرَ كُلَّهُۥ لِلَّهِ ۗ يُخْفُونَ فِىٓ أَنفُسِهِم مَّا لَا يُبْدُونَ لَكَ ۖ يَقُولُونَ لَوْ كَانَ لَنَا مِنَ ٱلْأَمْرِ شَىْءٌ مَّا قُتِلْنَا هَـٰهُنَا ۗ قُل لَّوْ كُنتُمْ فِى بُيُوتِكُمْ لَبَرَزَ ٱلَّذِينَ كُتِبَ عَلَيْهِمُ ٱلْقَتْلُ إِلَىٰ مَضَاجِعِهِمْ ۖ وَلِيَبْتَلِىَ ٱللَّهُ مَا فِى صُدُورِكُمْ وَلِيُمَحِّصَ مَا فِى قُلُوبِكُمْ ۗ وَٱللَّهُ عَلِيمٌۢ بِذَاتِ ٱلصُّدُورِ

Then after distress, He sent down upon you security [in the form of] drowsiness, overcoming a faction of you, while another faction worried about themselves, thinking of Allāh other than the truth - the thought of ignorance, saying, "Is there anything for us [to have done] in this matter?" Say, "Indeed, the matter belongs completely to Allāh." They conceal within themselves what they will not reveal to you. They say, "If there was anything we could have done in the matter, we [i.e., some of us] would not have been killed right here." Say, "Even if you had been inside your houses, those decreed to be killed would have come out to their death beds." [It was] so that Allāh might test what is in your breasts and purify what is in your hearts. And Allāh is Knowing of that within the breasts.

Ali 'Imran 154
