Tribute, Spoils, and Rulership (Kitab Al-Kharaj, Wal-Fai' Wal-Imarah)

Dawud :: Book 19 : Hadith 3065

Narrated Asmar ibn Mudarris:

I came to the Prophet (peace_be_upon_him), and took the oath of allegiance to him. He said: If anyone reaches a water which has not been approached before by any Muslim, it belongs to him. The people, therefore, went out running and marking (on the land).
