وَإِذَا دُعُوا إِلَى اللَّهِ وَرَسُولِهِ لِيَحْكُمَ بَيْنَهُمْAnd when they are called to Allah and His Messenger, to judge between them...means, when they are asked to follow the guidance which Allah has revealed to His Messenger, they turn away and are too arrogantly proud of themselves to follow him.This is like the Ayah:أَلَمْ تَرَ إِلَى الَّذِينَ يَزْعُمُونَ أَنَّهُمْ ءَامَنُواْ بِمَأ أُنزِلَ إِلَيْكَ وَمَأ أُنزِلَ مِن قَبْلِكَHave you not seen those who claim that they believe in that which has been sent down to you, and that which was sent down before you, until His saying:رَأَيْتَ الْمُنَـفِقِينَ يَصُدُّونَ عَنكَ صُدُوداًyou see the hypocrites turn away from you with aversion. (4:60-61)إِذَا فَرِيقٌ مِّنْهُم مُّعْرِضُونَlo! a party of them refuses and turns away. وَإِن يَكُن لَّهُمُ الْحَقُّ يَأْتُوا إِلَيْهِ مُذْعِنِينَ
