Malik reported: A man from the people of Kufa said that Umar ibn al-Khattab, may Allah be pleased with him, wrote to a commander in an army he had dispatched, saying, “I have heard that it is the habit of some of your men to chase an unbeliever until he takes refuge in a high place. Then a man tells him in Persian to not be afraid, and when he comes down, they kill him. By the One in whose hand is my soul, if I knew a man had done that once, I would strike his neck.”

عَنْ مَالِك عَنْ رَجُلٍ مِنْ أَهْلِ الْكُوفَةِ أَنَّ عُمَرَ بْنَ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ كَتَبَ إِلَى عَامِلِ جَيْشٍ كَانَ بَعَثَهُ إِنَّهُ بَلَغَنِي أَنَّ رِجَالًا مِنْكُمْ يَطْلُبُونَ الْعِلْجَ حَتَّى إِذَا أَسْنَدَ فِي الْجَبَلِ وَامْتَنَعَ قَالَ رَجُلٌ مَطْرَسْ يَقُولُ لَا تَخَفْ فَإِذَا أَدْرَكَهُ قَتَلَهُ وَإِنِّي وَالَّذِي نَفْسِي بِيَدِهِ لَا أَعْلَمُ مَكَانَ وَاحِدٍ فَعَلَ ذَلِكَ إِلَّا ضَرَبْتُ عُنُقَهُ
