Sahih al-Bukhari 2291

Abu Abd Allah said: Al-Layth narrated to me, from Jafar ibn Rabia, from Abd al-Rahman ibn Hurmuz, from Abu Huraira, from the Messenger of Allah (ﷺ), that he mentioned a man from among the Children of Israel who asked another man from among the Children of Israel to lend him one thousand dinars. The lender said, “Bring witnesses whom I can call to witness.” He replied, “Allah is sufficient as a witness.” The lender said, “Then bring me a guarantor.” He replied, “Allah is sufficient as a guarantor.” The lender said, “You have spoken truly,” and gave him the money for a specified term. The borrower traveled by sea and completed his business. Then he looked for a vessel to take him to the lender by the agreed due date, but could find none. He took a piece of wood, hollowed it out, put inside it one thousand dinars and a letter to his lender, and sealed the opening. Then he brought it to the sea and said, “O Allah, You know that I borrowed one thousand dinars from so-and-so. He asked me for a guarantor, and I said, ‘Allah is sufficient as a guarantor,’ and he accepted You. He asked me for a witness, and I said, ‘Allah is sufficient as a witness,’ and he accepted You. I tried hard to find a vessel to send him what is due to him, but I could not. I entrust it to You.” He cast the wood into the sea until it went out into it, then departed, still looking for a vessel to take him to his own land. The lender went out, hoping that a vessel had arrived with his money, and found the piece of wood containing the money. He took it home for firewood. When he split it open, he found the money and the letter inside. Then the borrower arrived, bringing one thousand dinars, and said, “By Allah, I kept trying to find a vessel to bring you your money, but I found no vessel before the one I came on.” The lender asked, “Had you sent me anything?” He replied, “I told you I found no vessel before the one I came on.” The lender said, “Allah has delivered on your behalf what you sent in the piece of wood. Go back with your one thousand dinars, rightly guided.”
