Abu Adi said: There was a dispute between Imru' al-Qays and a man, so the two of them brought their case to the Prophet (peace and blessings be upon him). He (peace and blessings be upon him) asked the Hadrami for evidence, but he had no evidence, so the Messenger of Allah (peace and blessings be upon him) ruled that Imru' al-Qays should take an oath. The Hadrami said: O Messenger of Allah! If you allow him to take the oath, by Allah, my land is gone. The Messenger of Allah (peace and blessings be upon him) said: "Whoever swears a false oath will meet Allah while He is angry with him." Raja' bin Haywah said: Then the Messenger of Allah (peace and blessings be upon him) recited this verse: "Indeed, those who sell the covenant of Allah and their oaths for a small price" (to the end of the verse) [Surah Al Imran: 77]. Imru' al-Qays said: O Messenger of Allah! What will I get if I give it up? He (peace and blessings be upon him) said: "Paradise." He said: Then I take you as my witness that I have given it up.
