Read and reflect on verse 4603 from Surah Al-Fath: [O you who believe!] God has promised you many war-gains which you shall yet achieve; and He has vouchsafed you these [worldly gains] well in advance,...
وَعَدَكُمُ اللَّهُ مَغَانِمَ كَثِيرَةً تَأْخُذُونَهَا فَعَجَّلَ لَكُمْ هَٰذِهِ وَكَفَّ أَيْدِيَ النَّاسِ عَنْكُمْ وَلِتَكُونَ آيَةً لِلْمُؤْمِنِينَ وَيَهْدِيَكُمْ صِرَاطًا مُسْتَقِيمًا
[O you who believe!] God has promised you many war-gains which you shall yet achieve; and He has vouchsafed you these [worldly gains] well in advance, and has stayed from you the hands of [hostile] people, so that this [your inner strength] may become a symbol to the believers [who will come after you], and that He may guide you all on a straight way.
