2:74
ثُمَّ قَسَتۡ قُلُوبُكُم مِّنۢ بَعۡدِ ذَ ٰلِكَ فَهِیَ كَٱلۡحِجَارَةِ أَوۡ أَشَدُّ قَسۡوَةࣰۚ وَإِنَّ مِنَ ٱلۡحِجَارَةِ لَمَا یَتَفَجَّرُ مِنۡهُ ٱلۡأَنۡهَـٰرُۚ وَإِنَّ مِنۡهَا لَمَا یَشَّقَّقُ فَیَخۡرُجُ مِنۡهُ ٱلۡمَاۤءُۚ وَإِنَّ مِنۡهَا لَمَا یَهۡبِطُ مِنۡ خَشۡیَةِ ٱللَّهِۗ وَمَا ٱللَّهُ بِغَـٰفِلٍ عَمَّا تَعۡمَلُونَ
Then, even after that, your hearts were hardened and became as rocks, or worse than rocks, for hardness. For indeed there are rocks from out which rivers gush, and indeed there are rocks which split asunder so that water floweth from them. And indeed there are rocks which fall down for the fear of Allah. Allah is not unaware of what ye do.
— Mohammed Marmaduke William Pickthall
