One of the principles of the Quranic economy is that the wealth or benefits must not concentrate among the rich few of the society. This principle can be derived from the following verses:
وَمَا أَفَاءَ اللَّهُ عَلَى رَسُولِهِ مِنْهُمْ فَمَا أَوْجَفْتُمْ عَلَيْهِ مِنْ خَيْلٍ وَلا رِكَابٍ وَلَكِنَّ اللَّهَ يُسَلِّطُ رُسُلَهُ عَلَى مَنْ يَشَاءُ وَاللَّهُ عَلَى كُلِّ شَيْءٍ قَدِيرٌ
مَا أَفَاءَ اللَّهُ عَلَى رَسُولِهِ مِنْ أَهْلِ الْقُرَى فَلِلَّهِ وَلِلرَّسُولِ وَلِذِي الْقُرْبَى وَالْيَتَامَى وَالْمَسَاكِينِ وَابْنِ السَّبِيلِ كَيْ لا يَكُونَ دُولَةً بَيْنَ الأغْنِيَاءِ مِنْكُمْ وَمَا آتَاكُمُ الرَّسُولُ فَخُذُوهُ وَمَا نَهَاكُمْ عَنْهُ فَانْتَهُوا وَاتَّقُوا اللَّهَ إِنَّ اللَّهَ شَدِيدُ الْعِقَابِ
"And whatever Allah has turned over to His Messenger from them, you did not toil on any horse or camel for it. But Allah gives His Messengers upper hand upon whom He wills. And Allah has devised measures for everything and He has full control over them.
Whatever Allah has turned over to His Messenger from those communities belongs to Allah and His Messenger (i.e. the Central Authority). [It shall be spent by the Messenger (i.e. the Head of the Islamic State) on]: (the 'Office' of) the Messenger, the welfare of the families of the believers, the orphans (,those who still feel left alone in the society, the widows), those who have no means of earning their livelihood, (the disabled who cannot move around looking for the Bounty of Allah), the homeless son of the street, ( those who are on their way to join you, or those who travel a distance to seek help). The expending will be in such a manner that it may not be [a benefit] going round and round among such of you as may [already] be rich. Hence, take what the Messenger gives you, and abstain from what he forbids you. Guard yourself against the harmful consequences of violating the Commands of Allah by careful observance. Verily, Allah is Stern in grasping." [59:6-7]
