Ali 'Imran 3:152

وَلَقَدۡ صَدَقَكُمُ ٱللَّهُ وَعۡدَهُۥٓ إِذۡ تَحُسُّونَهُم بِإِذۡنِهِۦۖ حَتَّىٰٓ إِذَا فَشِلۡتُمۡ وَتَنَٰزَعۡتُمۡ فِي ٱلۡأَمۡرِ وَعَصَيۡتُم مِّنۢ بَعۡدِ مَآ أَرَىٰكُم مَّا تُحِبُّونَۚ مِنكُم مَّن يُرِيدُ ٱلدُّنۡيَا وَمِنكُم مَّن يُرِيدُ ٱلۡأٓخِرَةَۚ ثُمَّ صَرَفَكُمۡ عَنۡهُمۡ لِيَبۡتَلِيَكُمۡۖ وَلَقَدۡ عَفَا عَنكُمۡۗ وَٱللَّهُ ذُو فَضۡلٍ عَلَى ٱلۡمُؤۡمِنِينَ 152

And Allah had certainly fulfilled His promise to you when you were killing the enemy by His permission until [the time] when you lost courage and fell to disputing about the order [given by the Prophet] and disobeyed after He had shown you that which you love. Among you are some who desire this world, and among you are some who desire the Hereafter. Then he turned you back from them [defeated] that He might test you. And He has already forgiven you, and Allah is the possessor of bounty for the believers
