﴿ ثُمَّ قَسَتْ قُلُوبُكُم مِّنۢ بَعْدِ ذَٰلِكَ فَهِىَ كَٱلْحِجَارَةِ أَوْ أَشَدُّ قَسْوَةًۭ ۚ 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 ﴾

“And yet, after all this, your hearts hardened and became like rocks, or even harder: for, behold, there are rocks from which streams gush forth; and, behold, there are some from which, when they are cleft, water issues; and, behold, there are some that fall down for awe of God And God is not unmindful of what you do!”

(Then, even after that) after bringing 'Amil back to life and informing you about his murderer, (your hearts were hardened) dry and barren (and became as rocks, or worse than rock, for hardness. For indeed there are rocks from out which rivers gush, and indeed there are some which split asunder so that water floweth from them. And indeed there are some which fall down) from the top of mountains to the bottom (for the fear of Allah) but your hearts are not moved by fear of Allah. (Allah is not unaware of) will not leave unpunished (what ye do) of transgressions; and it is said the meaning is: what you hide of transgression.
