Surah Al-Baqarah (2:74)
ثُمَّ قَسَتْ قُلُوبُكُم مِّنۢ بَعْدِ ذَٰلِكَ فَهِىَ كَٱلْحِجَارَةِ أَوْ أَشَدُّ قَسْوَةً وَإِنَّ مِنَ ٱلْحِجَارَةِ لَمَا يَتَفَجَّرُ مِنْهُ ٱلْأَنْهَٰرُ وَإِنَّ مِنْهَا لَمَا يَشَّقَّقُ فَيَخْرُجُ مِنْهُ ٱلْمَآءُ وَإِنَّ مِنْهَا لَمَا يَهْبِطُ مِنْ خَشْيَةِ ٱللَّهِ وَمَا ٱللَّهُ بِغَٰفِلٍ عَمَّا تَعْمَلُونَ
Then, after that, your hearts became hardened, so they were like stones, or even more intense in hardness. For indeed, among the stones is that from which rivers burst forth, and indeed among them is that which splits open so water comes out from it, and indeed among them is that which falls down from awe of Allah. And Allah is not at all unaware of what you do.
