Mudoraba — bu ikki kishi (yoki undan ortiq kishi) savdo-sotiqda ishtirok etadigan shartnoma bo‘lib, unda kapital ulardan biridan, mehnat esa ikkinchisidan bo‘ladi. Ya’ni bir kishining badani boshqa kishining mulki bilan sherik bo‘ladi. Bu degani, ishni ulardan biri bajaradi, ikkinchisi esa mulk beradi. Ikki sherik foydaning ma’lum bir ulushi bo‘yicha kelishib oladi. Masalan, ulardan biri ming funt beradi, ikkinchisi esa shu pul bilan ishlaydi va foyda ular o‘rtasida taqsimlanadi. Pul badan sherikka topshirilishi kerak, unga pul ustida erkin tasarruf huquqi beriladi, chunki mudoraba mulkni badan sherikka (mudorib) topshirishni talab qiladi. Mudorib mulk egasiga shart qo‘yish huquqiga ega: foydaning uchdan biri, yarmi yoki ular birgalikda foydaning belgilangan ulushi sifatida kelishib olgan har qanday miqdor uning. Chunki mudorib o‘z mehnati evaziga foydaga haqli bo‘ladi. Shunday qilib, sheriklar mudoribning foydasi oz yoki ko‘p bo‘lishidan qat’i nazar, kelishib olishlari joizdir. Demak, mudoraba mulk egalik qilishning qonuniy vositasi bo‘lgan bir turdagi mehnatdir. Mudorib, kelishuvga muvofiq o‘z mehnati tufayli mudoraba orqali foyda olgan mulkka shu tariqa egalik qiladi.

Mudharaba is where two persons (or more) participate in trading, where the capital comes from one of them and the work from the other. That is, the body of one person enters into partnership with the property of another person. This means that the work will be carried out by one of them and the other will provide the property. The two partners agree on a certain share of the profit. An example of this is when one of them provides one thousand pounds and the other person works with it, and the profit is divided between them. The money must be handed over to the body partner, who is given a free hand over the money, because Mudharaba requires the handing over of the property to the body partner (Mudharib). The body partner has the right to stipulate upon the property owner that He has a third, or half of the profit, or whatever they may agree on together as a defined portion of the profit. This is because the body partner (Mudharib) is entitled to the profit due to his work. It is thus allowed for the partners to agree on the profit of the Mudharib whether it is little or great. So Mudharaba is a kind of work which is a legal means of ownership. The Mudharib thus possesses the property, which He profited from via Mudharaba due to his work in accordance with what was agreed.
