2 : 74
ثُمَّ قَسَتۡ قُلُوبُكُم مِّنۢ بَعۡدِ ذَٰلِكَ فَهِيَ كَٱلۡحِجَارَةِ أَوۡ أَشَدُّ قَسۡوَةٗۚ وَإِنَّ مِنَ ٱلۡحِجَارَةِ لَمَا يَتَفَجَّرُ مِنۡهُ ٱلۡأَنۡهَٰرُۚ وَإِنَّ مِنۡهَا لَمَا يَشَّقَّقُ فَيَخۡرُجُ مِنۡهُ ٱلۡمَآءُۚ وَإِنَّ مِنۡهَا لَمَا يَهۡبِطُ مِنۡ خَشۡيَةِ ٱللَّهِۗ وَمَا ٱللَّهُ بِغَٰفِلٍ عَمَّا تَعۡمَلُونَ
Then your hearts became hardened after that, like rocks or even harder. There are rocks from which rivers gush forth, and there are others that split open from which water comes out, while others fall down out of humility to Allah. And Allah is not unaware of what you do.
