(Zukhuruf) 43 : 20
وَقَالُوا لَوْ شَاءَ الرَّحْمَٰنُ مَا عَبَدْنَاهُمْ ۗ مَا لَهُمْ بِذَٰلِكَ مِنْ عِلْمٍ ۖ إِنْ هُمْ إِلَّا يَخْرُصُونَ

They say: If the Impartial hadn’t intended, we wouldn’t have served them, they haven’t Knowledge regarding It; they are in nothing except in confusion.

The Fujjar are reading these verses in Arabic Qur’an.  But they by not trying to understand the Real Knowledge Adhikr are not having the confirmed belief about Allah, His Book, Messengers, Angels, and Hereafter. Thus they are serving Satan as explained in verses 36: 59-62, and are following conjectures and are in utter confusion as told in verse 6: 116. The verses they read, seen and heard will argue and witness against them and will push them in to the hell as explained in verse 9: 102.  See explanation 10: 60; 41: 19-25; and 45: 20.
