What hinders Us from sending a Verse (miracle) is only for the former ones to deny them (miracles). We gave to Thamûd nation the she-camel as a visible (miracle) but they did her wrong. And We do not send the Verses (miracles) but to scare.
We have told you that your Lord encompasses mankind (with His Mercy and Knowledge). We did not make the Vision which We showed you (with your heart’s eye) but a mischief (trial) for mankind and the cursed tree (the tree of Rosebay) in the Qur’ân as well. And We are scaring them. But this only adds to their great transgressions (sins).
And when We said to the angels: “Prostrate yourselves unto Adam”, they prostrated themselves except Iblîs (Lucifer). (Lucifer) said: “Shall I prostrate myself to one whom you created from clay?”
(Lucifer) said: “According to Your perspective, is this (creature) whom You have honored above me? If You delay me until the Day of Resurrection, I surely will cause his progeny to depend on me except a few.”
(Allah) said: “Leave! Whoever of them depends on you, then surely hell is your recompense as a full recompense.”
And beguile whomsoever of them you can with your voice. Steer them shouting with your cavalry and your infantry (towards hell). Be partners with them in their wealth and children. And make (false) promises to them. Satan makes promises for them only to deceive (to be arrogant).
Surely you have no authority over My servants. And your Lord is All Sufficient as a Surrogate.
Your Lord is He who drives the ships for you through the sea, in order that you may seek of His Virtue. Truly He is Ever Most Merciful towards you.
