The disposal of property is restricted by the permission of the Legislator (swt), for both of spending and investment. Squandering, extravagance and miserliness are all forbidden. Capitalist companies, co-operatives and any other type of transactions which contradict the Shari’ah are forbidden. Interest, fraud, monopolies, gambling and anything similar are all forbidden.

The evidence for this is the evidence regarding spending wealth and the evidence of verbal disposals of wealth such as selling, renting and so on, which are the evidences regarding increasing property.

As for the evidence of expenditure, Allah (swt) said:

“Let a man of wealth spend from his wealth.” (TMQ 65:7).

Regarding the prohibition of squandering, Allah (swt) said: “And be not excessive (extravagant). Indeed, He does not like those who commit excess.” (TMQ 7:31), and He (swt) said: “And do not spend wastefully; Indeed, the wasteful are brothers of the devils.” (TMQ 17:26-7).

With respect to the prohibition of miserliness, Allah (swt) said: “And [they are] those who, when they spend, do so not excessively or sparingly but are ever, between that, [justly] moderate.” (TMQ 25:67).

With respect to verbal disposals, the Legislator (swt) restricted them to specific transactions, such as selling, rent, partnership, and so on, and specified the manner they should be undertaken and prohibited any other method. The Prophet said:
