(61) And (remember) when We told you: "Verily! Your Lord has encompassed mankind (i.e. they are in His Grip)." And We made not the vision which we showed you (O Muhammad as an actual eye-witness and not as a dream on the night of Al-Isra' ) but a trial for mankind, and (likewise) the accursed tree (Zaqqum, mentioned) in the Qur'an.

(68) "Go to Fir'aun (Pharaoh)! Verily, he has transgressed (all bounds in disbelief and disobedience, and has behaved as an arrogant and as a tyrant)."

(69) "Go, both of you, to Fir'aun (Pharaoh), verily, he has transgressed (all bounds in disbelief and disobedience and behaved as an arrogant and as a tyrant).

(70) Nay, We fling (send down) the truth (this Qur'an) against the falsehood (disbelief), so it destroys it, and behold, it (falsehood) is vanished. And woe to you for that (lie) which you ascribe (to Allah by uttering that Allah has a wife and a son).
