Quran 3:152 from Surah Aal-i-Imraan on Divine Marvels.
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
English translation: And certainly fulfilled to you Allah His promise when you were killing them by His permission until when you lost courage and you fell into dispute concerning the order and you disobeyed from after [what] He (had) shown you what you love Among you (are some) who desire the world and among you (are some) who desire the Hereafter Then He diverted you from them so that He may test you And surely He forgave you And Allah (is the) Possessor (of) Bounty for the believers
