Ali 'Imran 3:152 ولقد صدقكم الله وعده اذ تحسونهم باذنه حتى اذا فشلتم وتنازعتم في الامر وعصيتم من بعد ما اراكم ما تحبون منكم من يريد الدنيا ومنكم من يريد الاخرة ثم صرفكم عنهم ليبتليكم ولقد عفا عنكم والله ذو فضل على المومنين ١٥٢

And Allâh did indeed fulfil His Promise to you when you were killing them (your enemy) with His Permission; until (the moment) you lost your courage and fell to disputing about the order, and disobeyed after He showed you (of the booty) which you love. Among you are some that desire this world and some that desire the Hereafter. Then He made you flee from them (your enemy), that He might test you. But surely, He forgave you, and Allâh is Most Gracious to the believers.
