[Machine] The Prophet ﷺ sent a man from his companions to a Jewish man to kill him. The man said, "O Messenger of Allah, allow me to speak." He then said, "Say whatever you think is appropriate, for war is a deceit."

بَعَثَ النَّبِيُّ ﷺ رَجُلًا مِنْ أَصْحَابِهِ إِلَى رَجُلٍ مِنَ الْيَهُودِ لِيَقْتُلَهُ فَقَالَ يَا رَسُولَ اللهِ ائْذَنْ لِي فَأَقُولَ فَقَالَ «قُلْ مَا بَدَا لَكَ فَإِنَّمَا الْحَرْبُ خَدْعَةٌ»

"عَنِ ابْن عَبَّاسٍ قَالَ: بَعَثَ رَسُولُ الله ﷺ رَجُلًا مِنْ أَصْحَابِهِ إِلَى رَجُلٍ مِنَ الْيَهُودِ فَأَمَرَهُ بِقَتلهِ، فَقَالَ لَهُ: يَا رَسُولَ الله إِنِّى لاَ أَسْتَطيعُ ذَلِكَ إِلاَّ أَنْ تَأذَنَ لِى، فَقَالَ رَسُولُ الله ﷺ إِنَّمَا الْحَرْبُ خِدْعَةٌ فَاصنَعْ مَا تُرِيدُ".
