Buraida reported the Prophet as saying, “When we appoint someone to an administrative post and provide him with an allowance, anything he takes beyond that is unfaithful dealing."
God’s Messenger sent me to the Yemen, but when I set off he sent after me and I was brought back. He then said, “Do you know why I sent for you? Do not take anything without my permission, for it is unfaithful dealing, and he who acts unfaithfully will come on the day of resurrection with the unfaithful deeds he has done. This is why I called you. Now go off to your task."
'A’isha told that when Abu Bakr became caliph he said, “My people know that my trade was not incapable of supporting my family, but I have become occupied with the affairs of the Muslims, so Abu Bakr’s family will be supported from this property while he works for it on behalf of the Muslims."
