Abu Dawud Book 13, Hadith Number 3060.

Narated By Abyad ibn Hammal : He asked the Apostle of Allah (PBUH) for giving him some land which had arak trees growing in it. The Apostle of Allah (PBUH) 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 (PBUH) 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.
