I could talk about any of these three, but I will talk about the one you probably not heard off – Khumus where the Quran gives Muhammad 20% of all the war bounty share (including women and children) before the remaining 80% is divided across the 10,000+ warriors! Making Muhammad richest person.
Read verse 8:41 in the Quran. It talks about the division of war spoils. After the battle, the fighters would bring all the spoils to Muhammad. Then one-fifth (Khumus) is set apart to Allah (I.e. Muhammad – not joking!!). That is why Muhammad used to announce after every fight, “These spoils belong to you, and I have no share in these for my own person except the “Khumus” which is spent for your common good. Therefore bring here everything-even a needle and its thread. Do not hide anything, big or small, for this is a shameful thing and leads to Hell” .
It is all good and dandy until you read in one of the the Hadith what they mean by the “Khumus”:
The Prophet (ﷺ) sent Ali to Khalid to bring the Khumus (of the booty) and I hated Ali, and Ali had taken a bath (after a sexual act with a slave-girl from the Khumus). I said to Khalid, “Don’t you see this (i.e. What Ali did)?” When we reached the Prophet (ﷺ) I mentioned that to him. He said, “O Buraida! Do you hate Ali?” I said, “Yes.” He said, “Do you hate him, for he deserves more than that from the Khumus.”
Sahih al-Bukhari 4350
And in case you did not know Saffiya, one of Muhammad’s wives, was also a war bounty taken the form of Khumus after one of these raids. She was the wife to be of the chief of the Jewish tribe. Muhammad went to pick up his Khumus. He saw how beautiful she is, so took her as his share! On the way back, he could not wait to reach his destination, he decided she was too attractive to risk anyone taking her, Muhammad rushed married her and nailed her that night!
