Surah Al-Imran, verse 152

وَلَقَدْ صَدَقَكُمُ ٱللَّهُ وَعْدَهُۥٓ إِذْ تَحُسُّونَهُم بِإِذْنِهِۦ ۖ حَتَّىٰٓ إِذَا فَشِلْتُمْ وَتَنَـٰزَعْتُمْ فِى ٱلْأَمْرِ وَعَصَيْتُم مِّنۢ بَعْدِ مَآ أَرَىٰكُم مَّا تُحِبُّونَ ۚ مِنكُم مَّن يُرِيدُ ٱلدُّنْيَا وَمِنكُم مَّن يُرِيدُ ٱلْـَٔاخِرَةَ ۚ ثُمَّ صَرَفَكُمْ عَنْهُمْ لِيَبْتَلِيَكُمْ ۖ وَلَقَدْ عَفَا عَنكُمْ ۗ وَٱللَّهُ ذُو فَضْلٍ عَلَى ٱلْمُؤْمِنِينَ ﴿١٥٢﴾

3:152 Indeed, Allah has fulfilled His promise to you when you were slaying them by His permission, until you lost courage and disputed over the command and disobeyed after He had shown you what you liked [victory]. Among you are some who seek this world and some who seek the Hereafter. He then prevented you from [defeating] them so that He may test You, but He pardoned you, for Allah is Most Gracious to the believers
