Hadith.3427 - Muhammad ibn Bahr al-Shaybani narrated from Abd al-Rahman ibn Ahmad al-Dhuhli, who said: Muhammad ibn Yahya al-Naysaburi narrated to us, who said: Abu al-Yaman al-Hakam ibn Nafi' al-Himsi narrated to us, who said: Shu'ayb narrated from al-Zuhri, from Abdullah ibn Ahmad al-Dhuhli, who said: 'Umara ibn Khuzayma ibn Thabit narrated to me that his uncle, who was one of the companions of the Prophet, peace be upon him and his family, said: The Prophet, peace be upon him and his family, purchased a horse from a Bedouin. The Prophet, peace be upon him and his family, walked quickly to pay him the price of the horse, but the Bedouin delayed. Meanwhile, some men intercepted the Bedouin and began bargaining with him for the horse, unaware that the Prophet, peace be upon him and his family, had already bought it. Some of them even offered the Bedouin a higher price. Then the Bedouin called out: "If you want to buy this horse, then buy it; otherwise, I will sell it to someone else." The Prophet, peace be upon him and his family, upon hearing this, said: "Did I not already buy it from you?" People began to gather around the Prophet, peace be upon him and his family, and the Bedouin, and they started disputing. The Bedouin said: "Bring a witness to testify that I sold it to you." Among the Muslims who arrived, they said to the Bedouin: "The Prophet, peace be upon him and his family, does not speak except the truth." Then Khuzayma ibn Thabit came forward, listened to the argument between the Prophet, peace be upon him and his family, and the Bedouin, and said: "I bear witness that you have sold it to him." The Prophet, peace be upon him and his family, turned to Khuzayma and said: "On what basis do you testify?" Khuzayma replied: "By affirming your truthfulness, O Messenger of Allah (swt)." Then the Prophet, peace be upon him and his family, declared the testimony of Khuzayma ibn Thabit equal to the testimony of two witnesses, and he called him 'Dhul Shahadatayn' (the possessor of two testimonies).
