Sayyiduna Abu Hurayrah (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "Two women had their children with them. A wolf took away the child of one of them. She said (to the other): The wolf has taken your son. The other said: The wolf has taken your son. The case came before Dawud (peace be upon him), and he judged in favour of the elder. They then passed by Sulayman bin Dawud (peace be upon him) and told him what had happened. He said: Bring a knife, and I will divide him between the two. The younger one said: May Allah have mercy on you, do not do that; the son is hers. So he judged in favour of the younger one." Sayyiduna Abu Hurayrah (may Allah be pleased with him) said: We had never heard the word "sikkin" (knife); we used to say "mudyah".
