The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
وَعَنْ أَنَسٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا غَزَا قَالَ: «اللَّهُمَّ أَنْتَ عَضُدِي وَنَصِيرِي بِكَ أَحُولُ وَبِكَ أَصُولُ وَبِكَ أُقَاتِلُ» . رَوَاهُ التِّرْمِذِيُّ وَأَبُو دَاوُد
Anas told that when God’s messenger went on an expedition he said, "O God, Thou art my aider and helper; by Thee I move, by Thee I attack, and by Thee I fight."
Tirmidhi and Abu Dawud transmitted it.
