Ma'mar said that al-Walid bin Yazid wrote to the governors of the cities that they should write to him about divorce before marriage, a matter with which he had been tried. So he wrote to his governor in Yemen. He summoned Ibn Tawus, Isma'il bin Sharus and Simak bin al-Fadl. Ibn Tawus reported from his father, Isma'il bin Sharus from Ata bin Abi Rabah, and Simak from Wahb bin Munabbih, that there is no divorce before marriage. Then Simak said on his own account: "Marriage is a knot that is tied, and divorce unties that knot; so how can a knot be untied before it is tied?" Al-Walid liked Simak's saying, adopted that very view, and wrote to his governor in Yemen to appoint him to the office of judge.
