Qur'an 3:152

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

“And Allāh had certainly fulfilled His promise to you when you were killing them [i.e., the enemy] by His permission until [the time] when you lost courage and fell to disputing about the order [given by the Prophet (ﷺ)] 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 Allāh is the possessor of bounty for the believers.”
