the essence flow in my vein

then after that your heart were hardened and become as stones,

or even worse in hardness.

and indeed, there are stones out of which rivers gush forth

and indeed, there are of them which split asunder so that water flows from them.

and indeed, there are one of them which fall down for fear of Allah,

and Allah is not unaware of what you do.

~alBaqarah, 74.
