Alqamah bin Wa'il bin Hujr al-Hadrami narrates from his father (Sayyiduna Wa'il bin Hujr (may Allah be pleased with him)) the story of the Hadrami and the Kindi: the Hadrami said: "O Messenger of Allah, this man has seized my father's land." The Kindi said: "It is my land; I cultivate it; he has no right in it." The Messenger of Allah (peace and blessings be upon him) asked the Hadrami: "Do you have any proof?" He said: No. So he (peace and blessings be upon him) said: "Then you are entitled to the Kindi's oath."
