فَإِنْ أَمِنَ بَعْضُكُم بَعْضًا فَلْيُؤَدِّ الَّذِى اؤْتُمِنَ أَمَـنَتَهُ
(Then if one of you entrusts the other, let the one who is entrusted discharge his trust (faithfully).) Or, it could be that having witnesses in such cases is only recommended and not obligatory, as evident from the Hadith that Khuzaymah bin Thabit Al-Ansari narrated which Imam Ahmad collected. `Umarah bin Khuzaymah Al-Ansari said that his uncle, who was among the Prophet's Companions, told him that the Prophet was making a deal for a horse with a bedouin man. The Prophet asked the bedouin to follow him so that he could pay him the price of the horse. The Prophet went ahead of the bedouin. The bedouin met several men who tried to buy his horse, not knowing if the Prophet was actually determined to buy it. Some people offered more money for the horse than the Prophet had. The bedouin man said to the Prophet , â€If you want to buy this horse, then buy it or I will sell it to someone else.'' When he heard the bedouin man's words, the Prophet stood up and said, â€Have I not bought that horse from you'' The bedouin said, â€By Allah! I have not sold it to you.'' The Prophet said, â€Rather, I did buy it from you.'' The people gathered around the Prophet and the Bedouin while they were disputing, and the bedouin said, â€Bring forth a witness who testifies that I sold you the horse.'' Meanwhile, the Muslims who came said to the bedouin, â€Woe to you! The Prophet only says the truth.'' When Khuzaymah bin Thabit came and heard the dispute between the Prophet and the bedouin who was saying, â€Bring forth a witness who testifies that I sold you the horse, '' Khuzaymah said, â€I bear witness that you sold him the horse.'' The Prophet said to Khuzaymah, â€What is the basis of your testimony'' Khuzaymah said, â€That I entrusted you, O Messenger of Allah!'' Therefore, the Messenger made Khuzaymah's testimony equal to the testimony of two men. This was also recorded by Abu Dawud and An-Nasa ®299Ø›. Allah's statement,
