Surat al-An`am: 111-117, relevant to current events.
“Even if We did send unto them angels, and the dead did speak unto them, and We gathered together all things before their very eyes, they are not the ones to believe, unless it is in Allah’s plan. But most of them ignore (the truth).
“Likewise did We make for every Messenger an enemy,- evil ones among men and jinns, inspiring each other with flowery discourses by way of deception. If thy Lord had so planned, they would not have done it: so leave them and their inventions alone.
“To such (deceit) let the hearts of those incline, who have no faith in the hereafter: let them delight in it, and let them earn from it what they may.
“Say: “Shall I seek for judge other than Allah? – when He it is Who hath sent unto you the Book, explained in detail.” They know full well, to whom We have given the Book, that it hath been sent down from thy Lord in truth. Never be then of those who doubt.
“The word of thy Lord doth find its fulfilment in truth and in justice: None can change His words: for He is the one who heareth and knoweth all.
“Wert thou to follow the common run of those on earth, they will lead thee away from the way of Allah. They follow nothing but conjecture: they do nothing but lie.
“Thy Lord knoweth best who strayeth from His way: He knoweth best who they are that receive His guidance.”
