Ahmed Raza Khan: Mohammed Aqib Qadri:
Then after it, your hearts hardened - so they are like rocks, or even harder; for there are some rocks that rivers gush forth from them; and some that water flows from them when they split asunder; and there are rocks that fall down for the fear of Allah; and Allah is not unaware of your deeds.
Yusuf Ali:
Thenceforth were your hearts hardened: They became like a rock
and even worse in hardness. For among rocks there are some from which
rivers gush forth; others there are which when split asunder send forth
water; and others which sink for fear of Allah. And Allah is not unmindful of
what ye do.
Pickthal:
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.
