[Machine] The Messenger of Allah ﷺ said on the day of Badr: "Whoever kills a person, he will have such and such, and whoever takes a captive, he will have such and such." Then, he continued speaking, and this is contrary to the first in the conditionality, and we have narrated about the spoils of Badr that it happened before the revelation of the fifth, then the verse was revealed: "And know that anything you obtain of war booty - then indeed, for Allah is one fifth of it" (Quran 8:41), so the matter was changed to that. And with Allah is the success.  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ يَوْمَ بَدْرٍ مَنْ قَتَلَ قَتِيلًا فَلَهُ كَذَا وَكَذَا وَمَنْ أَسَرَ أَسِيرًا فَلَهُ كَذَا وَكَذَا قَالَ ثُمَّ سَاقَ الْحَدِيثَ وَهَذَا بِخِلَافِ الْأَوَّلِ فِي كَيْفِيَّةِ الشَّرْطِيَّةِ وَقَدْ رُوِّينَا فِي غَنِيمَةِ بَدْرٍ أَنَّهَا كَانَتْ قَبْلَ نُزُولِ الْخُمُسِ ثُمَّ نَزَلَ قَوْلُهُ {وَاعْلَمُوا أَنَّمَا غَنِمْتُمْ مِنْ شَيْءٍ فَأَنَّ لِلَّهِ خُمُسَهُ} [الأنفال 41] الْآيَةَ فَصَارَ الْأَمْرُ إِلَيْهِ وَبِاللهِ التَّوْفِيقُ
