Sura Āl-ʿImrān 3:153

إِذْ تُصْعِدُونَ وَلَا تَلْوُۥنَ عَلَىٰٓ أَحَدٍ وَٱلرَّسُولُ يَدْعُوكُمْ فِىٓ أُخْرَىٰكُمْ فَأَثَٰبَكُمْ غَمًّۢا بِغَمٍّ لِّكَيْلَا تَحْزَنُوا۟ عَلَىٰ مَا فَاتَكُمْ وَلَا مَآ أَصَٰبَكُمْ وَٱللَّـهُ خَبِيرٌۢ بِمَا تَعْمَلُونَ

idh tuṣʿidūna wa-lā talwuna ʿala aḥadin wal-rasūlu yadʿūkum fī ukhrakum faathābakum ghamman bi-ghammin llikaylā taḥzanū ʿalā mā fātakum wa-lā mā aṣābakum wallāhu khabīrun bi-mā taʿmalūna

Behold! ye were climbing up the high ground, without even casting a side glance at any one, and the Messenger in your rear was calling you back. There did Allah give you one distress after another by way of requital, to teach you not to grieve for (the booty) that had escaped you and for (the ill) that had befallen you. For Allah is well aware of all that ye do.
