财产是指任何可以被拥有的东西，无论其性质如何。取得财产的途径，是最初使财产归属于某人的原因。交换，无论以何种形式出现，都不被视为取得财产的途径之一。它是通过交换某一特定财产中的部分物品来获得其他物品的方式，而该财产原本已经属于其所有者。同样，财产的投资，例如经商所得的利润、房屋的租金以及农作物的收成，也不被视为取得财产的途径之一。虽然某些财产因这种投资而新生，但它是从另一项财产衍生出来的，因此投资属于增加财产的途径，而不是取得财产的途径。本文所讨论的主题是财产的最初取得，换言之，即原始财产的获得。

Property is anything that can be possessed, whatever its nature. The means of its possession is the cause, which initiated the ownership of the property to the person in the first place. Exchange, in all its forms, is not considered as one of the means of possessing property. It is a means of possessing commodities through the exchange of a particular commodity of property, where the property was originally in possession, but some of its commodities were exchanged. Investment of property such as the profit from trading, the rental of houses, and the harvest of crops, similarly is not considered as one of the means of possessing property. Though some property has been generated anew by this investment, it was initiated from another property, so investment is from the means of increasing the property, and not the means of possessing the property. The subject at hand is the initial possession of the property, in other words the acquisition of the original property.

占有的途径与对已有财产进行投资的途径之间的区别在于：占有是最初获得财产，即取得其来源；而对已拥有的财产进行投资，则是增加已经拥有的财产。财产本身已经存在，只是被投入运作并得到增长。伊斯兰教法既为财产的拥有制定了规则，也为对已拥有财产的投资制定了规则。买卖和租赁等契约属于财产投资方面的规则，狩猎和合伙（无声合伙）等行为则属于财产占有方面的规则。因此，拥有的途径就是取得原始财产的途径，而投资已拥有财产的途径则是增加财产的途径，这些财产此前已通过某种拥有途径而被拥有。
