Abu Dawud Book 13, Hadith Number 3070.

Chapter : Not known.

Narated By Urwah : I testify that the Apostle of Allah (PBUH) decided that the land is the land of Allah, and the servants are the servants of Allah. If anyone brings barren land into cultivation, he has more right to it.

This tradition has been transmitted to us from the Prophet (PBUH) by those who transmitted the traditions about prayer from him.
