Hadith.3246 - In the narration of Amr ibn Shimr, from Jafar ibn Ghalib al-Asadi, who reported: Two men were sitting during the time of Umar ibn al-Khattab when a man passed by them in chains. One of the men said: "If there is not such-and-such weight in his chains, then my wife is divorced three times." The other man said: "If there is such-and-such weight in his chains as you said, then my wife is divorced three times." They went to the owner of the chained slave and said: "We have sworn oaths regarding such-and-such, so release the chain of your slave so that we may weigh it." The owner of the slave said: "My wife will be divorced if I release the chain of my slave." So, they went to Umar and told him the story. Umar said: "The owner has more right over his slave. Go to Ali ibn Abi Talib - perhaps he has something regarding this matter." They went to Imam Ali ibn Abi Talib and told him the story. Imam said: "How simple this is!" Imam called for a large basin and ordered the chain to be tied with a string and placed in the basin. Then Imam put the man's feet and the chain into the basin and filled it with water until it was full. Then Imam said: "Lift the chain." When they lifted the chain out of the water, the water level dropped. Imam then called for pieces of iron and placed them into the water until the water level returned to its original position. Then Imam said: "Weigh these pieces of iron-they are equal in weight to the chain."
