Here is where the title of this Sura comes from:
He it is Who drove out the disbelievers among the people of the Scripture (i.e. the Jews of the tribe of Banî An-Nadîr) from their homes at the first gathering. You did not think that they would get out. And they thought that their fortresses would defend them from Allâh! But Allâh’s (Torment) reached them from a place whereof they expected it not, and He cast terror into their hearts, so that they destroyed their own dwellings with their own hands and the hands of the believers. Then take admonition, O you with eyes (to see). (Al-Hashr 59:2)

Allah distributing the wealth????:
And what Allâh gave as booty (Fai’) to His Messenger (Muhammad SAW) from them, for which you made no expedition with either cavalry or camelry. But Allâh gives power to His Messengers over whomsoever He wills. And Allâh is Able to do all things. (Al-Hashr 59:6)
What Allâh gave as booty (Fai’) to His Messenger (Muhammad SAW) from the people of the townships, – it is for Allâh, His Messenger (Muhammad SAW), the kindred (of Messenger Muhammad SAW), the orphans, Al­Masâkin (the poor), and the wayfarer, in order that it may not become a fortune used by the rich among you. And whatsoever the Messenger (Muhammad SAW) gives you, take it, and whatsoever he forbids you, abstain (from it), and fear Allâh. Verily, Allâh is Severe in punishment. (Al-Hashr 59:7)
(And there is also a share in this booty) for the poor emigrants, who were expelled from their homes and their property, seeking Bounties from Allâh and to please Him. And helping Allâh (i.e. helping His religion) and His Messenger (Muhammad SAW). Such are indeed the truthful (to what they say);- (Al-Hashr 59:8)
And those who, before them, had homes (in Al-Madinah) and had adopted the Faith, love those who emigrate to them, and have no jealousy in their breasts for that which they have been given (from the booty of Banî An-Nadîr), and give them (emigrants) preference over themselves, even though they were in need of that. And whosoever is saved from his own covetousness, such are they who will be the successful. (Al-Hashr 59:9)
