Apostate prophet is getting closer; Islamic social brotherhood?

In answer to the video "Islamic Slavery"

This system of having different grades and needs among the people, is the consequence of a chain of causality established by Allah. It ultimately creates a web of interdependant diversity necessary for one of the aspects of divine trials; our dealings with eachother. Many fail to perceive this ultimate reality and they are referred to in

36:47"And when it is said to them: Spend out of what Allah has given you, those who disbelieve say to those who believe: Shall we feed him whom, if Allah please, He could feed? You are in naught but clear error".

God does indeed will for the deprived and weak to be helped, but according to the laws He has established and that benefit both the one who freely offers his help (emotional, material, physical, spiritual, intellectual), as well as the receiver of that help. Others raise an outcry and question divine justice in light of the fact that people are born with varying degrees of socio-economical as well as psycho-physical conditions. That questioning is answered through the divine scheme explained above, as well as the Quranic concept that

2:156"Indeed, we belong to Allah and indeed we towards Him will return".

Our whole self belongs to Him and He in reality doesnt owe us a single thing, whatever we receive from Him, since birth and throughout life, little or big, is a favor from Him and serves a higher purpose which can only be beneficial if one accepts God's supreme ownership

11:9"If We make man taste mercy from Ourselves, (and) then take it off from him, verily he is despairing ungrateful".

Neither self-conceit nor despair are appropriate if one admits that all things belong to God and return to Him when He decides.

The unbelievers of the time of the prophet disregarded lower social classes, disrespected and discriminated them. They mocked the assemblies of poor people and ex-slaves listening to the prophet, just like prophets were reproached before, the likes of Nuh 11:27-30, assuming that if Allah had truly sent revelation then why didnt He address the elite and rulers of whom Muhammad was not 43:31? In their limited, materialistic mindframe they considered themselves more deserving of divine favors

6:53"And thus do We try some of them by others so that they say: Are these they upon whom Allah has conferred benefit from among us? Does not Allah best know the grateful?".
