3. Ali Imran · verses 166–167

وَمَآ أَصَٰبَكُمۡ يَوۡمَ ٱلۡتَقَى ٱلۡجَمۡعَانِ فَبِإِذۡنِ ٱللَّهِ وَلِيَعۡلَمَ ٱلۡمُؤۡمِنِينَ

Wama asabakum yawma iltaqa aljamAAani fabiithni Allahi waliyaAAlama almumineena

What ye suffered on the day the two armies Met, was with the leave of Allah, in order that He might test the believers,-

وَلِيَعۡلَمَ ٱلَّذِينَ نَافَقُواْۚ وَقِيلَ لَهُمۡ تَعَالَوۡاْ قَٰتِلُواْ فِي سَبِيلِ ٱللَّهِ أَوِ ٱدۡفَعُواْۖ قَالُواْ لَوۡ نَعۡلَمُ قِتَالٗا لَّٱتَّبَعۡنَٰكُمۡۗ هُمۡ لِلۡكُفۡرِ يَوۡمَئِذٍ أَقۡرَبُ مِنۡهُمۡ لِلۡإِيمَٰنِۚ يَقُولُونَ بِأَفۡوَٰهِهِم مَّا لَيۡسَ فِي قُلُوبِهِمۡۚ وَٱللَّهُ أَعۡلَمُ بِمَا يَكۡتُمُونَ

WaliyaAAlama allatheena nafaqoo waqeela lahum taAAalaw qatiloo fee sabeeli Allahi awi idfaAAoo qaloo law naAAlamu qitalan laittabaAAnakum hum lilkufri yawmaithin aqrabu minhum lileemani yaqooloona biafwahihim ma laysa fee quloobihim waAllahu aAAlamu bima yaktumoona

And the Hypocrites also. These were told: "Come, fight in the way of Allah, or (at least) drive (The foe from your city)." They said: "Had we known how to fight, we should certainly have followed you." They were that day nearer to Unbelief than to Faith, saying with their lips what was not in their hearts but Allah hath full knowledge of all they conceal.
