﴿ وَمِنَ ٱلنَّاسِ مَن يُجَٰدِلُ فِى ٱللَّهِ بِغَيْرِ عِلْمٍۢ وَلَا هُدًۭى وَلَا كِتَٰبٍۢ مُّنِيرٍۢ ﴾

“And yet, among men there is many a one that argues about God without having any knowledge [of Him], without any guidance, and without any light-giving revelation –”

(And among mankind is he who disputeth concerning Allah) argues against Allah's religion and Scripture (without knowledge or guidance) or proof (or a Scripture giving light) or Scripture expositing what he says.
