Surah 21. Al-Anbiya, Ayah 67

As soon as they admitted in so many words that the idols could not speak, Abraham delivered his final attack: 'Then why do you worship useless impotent creatures?' After that, there remains nothing but the argument of violence, which they proceed to exercise, being the party in power. 'Burn him at the stake' is an easy cry! But it was not Abraham that suffered: it was his persecutors (xxi. 70).
