Then (even) after this your hearts hardened. So (in hardness) they (have become) like stones or even harder. For of stones there are some from which streams burst out; and, certainly, some out of them are such (stones) that split up and water gushes out of them; and indeed there are others of them that fall due to fear of Allah. (Alas! Your hearts have not remained even that much soft, tender and feeble) and Allah is not unaware of what you do.
