‘A’isha reported the Prophet as saying, “He who develops land which has no owner has the best right to it.” ‘Urwa said that ‘Umar gave decision accordingly during his caliphate.
‘Ubada b. as-Samit told that he said, “Messenger of God, one of those whom I have been teaching the Book and the Qur’an has presented me with a bow, and as it cannot be reckoned property may I shoot with it in God's path?" He replied, “If you want to have a necklace of fire put on you, accept it."
‘Utba b. al-Mundhir said that once when they were with God’s Messenger he recited Ta’ Sin Mim (Al-Qur’an 28. The passage about Moses hiring himself is verses 26 to 28) till he came to the story of Moses and said, “Moses hired himself for eight or ten years in return for preserving his chastity and receiving his food."
