15th Ayah from Surah Al Qasas
Sahih International
And he entered the city at a time of inattention by its people and found therein two men fighting: one from his faction and one from among his enemy. And the one from his faction called for help to him against the one from his enemy, so Moses struck him and [unintentionally] killed him. [Moses] said, "This is from the work of Satan. Indeed, he is a manifest, misleading enemy."
Abdul Haleem
He entered the city, unnoticed by its people, and found two men fighting: one from his own people, the other an enemy. The one from his own people cried out to him for help against the enemy. Moses struck him with his fist and killed him. He said, ‘This must be Satan’s work: clearly he is a misleading enemy.’
Mohsin Khan/Hilali
And he entered the city at a time of unawareness of its people, and he found there two men fighting, - one of his party (his religion - from the Children of Israel), and the other of his foes. The man of his (own) party asked him for help against his foe, so Musa (Moses) struck him with his fist and killed him. He said: "This is of Shaitan's (Satan) doing, verily, he is a plain misleading enemy."
Taqi Usmani
Once he entered the city at a time when its people were heedless; so he found in it two men fighting each other: This one was from his own group, and that one from his enemies. So the one from his own group called him for help against the one who was from his enemies. So Mūsā gave him a blow with his fist and finished him off. (Then) He (Mūsā) said (out of remorse), “This is some of Satan’s act. He is indeed a clear enemy who misleads (people).”

And he entered the city at a time of carelessness of its folk, and he found therein two men fighting, one of his own caste, and the other of his enemies; and he who was of his caste asked him for help against him who was of his enemies. So Moses struck him with his fist and killed him. He said: This is of the devil's doing. Lo! he is an enemy, a mere misleader.
Pickthall
And he entered the city at a time when its people were not watching: and he found there two men fighting,- one of his own religion, and the other, of his foes. Now the man of his own religion appealed to him against his foe, and Moses struck him with his fist and made an end of him. He said: "This is a work of Evil (Satan): for he is an enemy that manifestly misleads!"
