The Messenger of Allah (sal Allahu alaihi wa sallam) said: "He who holds a monopoly is a sinner." [Sahih Muslim]
A Muslim is one who likes for others what he likes for himself. To hoard and monopolize what others need, and over-charge for it, contradicts the character that Allah (Subhanahu wa ta'ala) wants us to develop and exhibit towards each other. A Muslim cannot be a capitalist, because for him Allah's pleasure has the highest priority, not money.
There is no shortage with Allah (Subhanahu wa ta'ala). So instead of squeezing what you want out of other people, ask Allah (Subhanahu wa ta'ala) to give it to you.
As salaamu'alaikum waRahmatullah waBarakaatuhu:-)
