Tribute, Spoils, and Rulership (Kitab Al-Kharaj, Wal-Fai' Wal-Imarah)
Dawud :: Book 19 : Hadith 3060
Narrated Abyad ibn Hammal:
He asked the Apostle of Allah (peace_be_upon_him) for giving him some land which had arak trees growing in it. The Apostle of Allah (peace_be_upon_him) said: There is no (permission for) protecting a land which has arak trees growing in it. He said: These arak trees are within the boundaries of my field. The Prophet (peace_be_upon_him) said: There is no (permission for) protecting a land which has arak trees growing in it.
The narrator Faraj said: By the phrase 'within the boundaries of my field' he meant the land which had crop growing in it and was surrounded on four sides.
