Suraatul Baqaraah, Verses 72 – 74
72. And (remember) when you killed a man and fell into dispute among yourselves as to the crime. But Allah brought forth that which you were hiding.
73. So We said: “Strike him (the dead man) with a piece of it (the cow).” Thus Allah brings the dead to life and shows you HisAyat (proofs, evidences, verses, lessons, signs, revelations, etc.) so that you may understand.
74. Then, after that, your hearts were hardened and became as stones or even worse in hardness. And indeed, there are stones out of which rivers gush forth, and indeed, there are of them (stones) which split asunder so that water flows from them, and indeed, there are of them (stones) which fall down for fear of Allah. And Allah is not unaware of what you do.
