It is recommended to pray for victory when meeting the enemy
وَحَدَّثَنَاهُ إِسْحَاقُ بْنُ إِبْرَاهِيمَ، وَابْنُ أَبِي عُمَرَ، جَمِيعًا عَنِ ابْنِ عُيَيْنَةَ، عَنْ إِسْمَاعِيلَ، بِهَذَا الإِسْنَادِ وَزَادَ ابْنُ أَبِي عُمَرَ فِي رِوَايَتِهِ " مُجْرِيَ السَّحَابِ " .
This hadith has been narrated on the authority of Ibn 'Uyaina through another chain of transmitters (who added the words)" the Disperser of clouds" in his narration.
