Their hearts became hard after these great lessons and incredible miracles, until they became like rocks, and even harder than rocks, because they never changed, whereas rocks change and transform. Rivers spring from some rocks, and some split, and water comes out of them, gushing and flowing on the earth, benefitting people and animals. And some rocks fall from the heights of the mountains in awe of Allah. But their hearts were not like that. Allah is not unaware of anything we do, but knows everything, and will hold us to account for it.
