The Holy Prophet’s supplication when encountering the enemy

عَنْ أَنَسِ بْنِ مَالِكٍ قَالَ، كَانَ رَسُوْلُ اللہِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ إِذَا غَزَا قَالَ اللّٰهُمَّ أَنْتَ عَضُدِیْ وَنَصِيْرِیْ بِكَ أَحُوْلُ وَبِكَ أَصُوْلُ وَبِكَ أُقَاتِلُ

Hazrat Anas ibn Malik^ra narrates:

“When the Holy Prophet^sa went on an expedition, he said: ‘O Allah, Thou art my Aid and Helper; by Thee I move, by Thee I advance, and by Thee I fight.’”

(Sunan Abi Dawud, Kitab al-Jihad, Hadith 2632)
