وَلِيَعْلَمَ ٱلَّذِينَ نَافَقُواْۚ وَقِيلَ لَهُمْ تَعَالَوْاْ قَـٰتِلُواْ فِى سَبِيلِ ٱللَّهِ أَوِ ٱدْفَعُواْۖ قَالُواْ لَوْ نَعْلَمُ قِتَالاً لَّٱتَّبَعْنَـٰكُمْۗ هُمْ لِلْكُفْرِ يَوْمَئِذٍ أَقْرَبُ مِنْهُمْ لِلْإِيمَـٰنِۚ يَقُولُونَ بِأَفْوَٲهِهِم مَّا لَيْسَ فِى قُلُوبِهِمْۗ وَٱللَّهُ أَعْلَمُ بِمَا يَكْتُمُونَ ١٦٧
And that He might know the hypocrites, unto whom it was said: Come, fight in the way of Allah, or defend yourselves. They answered: If we knew aught of fighting we would follow you. On that day they were nearer disbelief than faith. They utter with their mouths a thing which is not in their hearts. Allah is Best Aware of what they hide.
