Abu Hurairah narrated that:
The Messenger of Allah [SAW] said: There were two woman who had two children, and the wolf came and took away the son of one of them. She said to her companion: 'It took away your son.' The other one said: 'No, it took away your son.' They referred the matter to Dawud, peace be upon him, for judgment (about the remaining child) and he ruled in favor of the older one. Then they went out to Sulaiman bin Dawud and told him (about that). He said: 'Give me a knife and I will cut him in half (to be shared) between you.' The younger one said: 'Do not do that, may Allah have mercy on you; he is her son.' So he ruled that (the child) belonged to the younger woman. Abu Hurairah said: By Allah! I never heard 'Sikkin' used until that day. We would only say: 'Mudyah.'
