Al ‘Imrân 3:167
وَلِيَعْلَمَ الَّذِينَ نَافَقُوا ۚ وَقِيلَ لَهُمْ تَعَالَوْا قَاتِلُوا فِي سَبِيلِ اللَّهِ أَوِ ادْفَعُوا ۖ قَالُوا لَوْ نَعْلَمُ قِتَالًا لَّاتَّبَعْنَاكُمْ ۗ هُمْ لِلْكُفْرِ يَوْمَئِذٍ أَقْرَبُ مِنْهُمْ لِلْإِيمَانِ ۚ يَقُولُونَ بِأَفْوَاهِهِم مَّا لَيْسَ فِي قُلُوبِهِمْ ۗ وَاللَّهُ 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.” (3:167)
