Qur'an 8:41

۞ وَٱعْلَمُوٓا۟ أَنَّمَا غَنِمْتُم مِّن شَىْءٍ فَأَنَّ لِلَّهِ خُمُسَهُۥ وَلِلرَّسُولِ وَلِذِى ٱلْقُرْبَىٰ وَٱلْيَتَـٰمَىٰ وَٱلْمَسَـٰكِينِ وَٱبْنِ ٱلسَّبِيلِ إِن كُنتُمْ ءَامَنتُم بِٱللَّهِ وَمَآ أَنزَلْنَا عَلَىٰ عَبْدِنَا يَوْمَ ٱلْفُرْقَانِ يَوْمَ ٱلْتَقَى ٱلْجَمْعَانِ ۗ وَٱللَّهُ عَلَىٰ كُلِّ شَىْءٍ قَدِيرٌ

“And know that anything you obtain of war booty - then indeed, for Allāh is one fifth of it and for the Messenger and for [his] near relatives and the orphans, the needy, and the [stranded] traveler, if you have believed in Allāh and in that which We sent down to Our Servant on the day of criterion [i.e., decisive encounter] - the day when the two armies met [at Badr]. And Allāh, over all things, is competent.”
