They will not fight you (even) together, except in fortified townships, or from behind walls. Strong is their fighting (spirit) amongst themselves: thou wouldst think they were united, but their hearts are divided: that is because they are a people devoid of wisdom. [59:14]

What Allah has bestowed on His Apostle (and taken away) from the people of the townships,- belongs to Allah,- to His Apostle and to kindred and orphans, the needy and the wayfarer; In order that it may not (merely) make a circuit between the wealthy among you. So take what the Apostle assigns to you, and deny yourselves that which he withholds from you. And fear Allah; for Allah is strict in Punishment. [59:7]
