﴿ وَقَدْ كَفَرُوا۟ بِهِۦ مِن قَبْلُ ۖ وَيَقْذِفُونَ بِٱلْغَيْبِ مِن مَّكَانٍۭ بَعِيدٍۢ ﴾

“seeing that aforetime they had been bent on denying the truth, and had been wont to cast scorn, from far away, on something that was beyond the reach of human perception?”

when they disbelieved in it before? in this world. And they throw guesses at the Unseen from a far-off place in other words they make guesses about something the knowledge of which was hidden far away from them as when they would say that the Prophet was a sorcerer or a poet or a soothsayer or that the Qur’ān was sorcery poetry or soothsaying.
