Al-Qasas 28:15

<h2>How Musa killed a Coptic Man</h2><p>Having described Musa's beginnings, Allah then tells us that when he reached maturity, and was complete in stature, Allah gave him Hukm and religious knowledge. Mujahid said that this means prophethood.</p><div class="arabic uthmani">وَكَذَلِكَ نَجْزِى الْمُحْسِنِينَ</div><p>(And thus do We reward the doers of good.) Then Allah describes how Musa reached the status that was decreed for him, that of Prophethood and speaking to Allah, as a direct consequence of killing the Coptic, which was the reason why he left Egypt and went to Madyan. Allah says:</p><div class="arabic uthmani">وَدَخَلَ الْمَدِينَةَ عَلَى حِينِ غَفْلَةٍ مِّنْ أَهْلِهَا</div><p>(And he entered the city when its people were unaware.) Ibn Jurayj narrated from `Ata' Al-Khurasani, from Ibn `Abbas, "That was between Maghrib and `Isha'." Ibn Al-Munkadir narrated from `Ata' bin Yasar from Ibn `Abbas, "That was in the middle of the day." This was also the view of Sa`id bin Jubayr, `Ikrimah, As-Suddi and Qatadah.</p><div class="arabic uthmani">فَوَجَدَ فِيهَا رَجُلَيْنِ يَقْتَتِلاَنِ</div><p>(and he found there two men fighting,) meaning, hitting one another and struggling with one another.</p><div class="arabic uthmani">هَـذَا مِن شِيعَتِهِ</div><p>(one of his party, ) meaning, an Israelite,</p><div class="arabic uthmani">وَهَـذَا مِنْ عَدُوِّهِ</div><p>(and the other of his foes.) meaning, a Coptic. This was the view …

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.

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!"

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."

Once he entered the city, unnoticed by its people. He found in it two men fighting—one of his own sect, and one from his enemies. The one of his sect solicited his assistance against the one from his enemies; so Moses punched him, and put an end to him. He said, “This is of Satan's doing; he is an enemy that openly misleads.”
