Sahih Bukhari | Volume 5 | Hadith Number 542

Narrated by 'Umar bin Al-Khattab
By Him in Whose Hand my soul is, were I not afraid that the other Muslims might be left in poverty, I would divide (the land of) whatever village I may conquer (among the fighters), as the Prophet divided the land of Khaibar. But I prefer to leave it as a (source of) a common treasury for them to distribute it revenue amongst themselves.
