Musnad Ahmad Hadith 8280

It is narrated from Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (ﷺ) said: There were two women, and with them were their two sons. Suddenly, a wolf came from somewhere and took away one of the boys. Both of them brought their case before Dawood (peace be upon him). He decided that the remaining child belonged to the elder woman. As they were leaving, Sulaiman (peace be upon him) called them and said, "Bring a knife, I will divide this child into two parts and give them to you." Upon hearing this, the younger woman said, "May Allah have mercy on you, he is her child (at least he will remain alive); do not divide him into two parts." Thus, Sulaiman (peace be upon him) decided in favor of the younger woman. Abu Hurairah (may Allah be pleased with him) says: By Allah, the word "sikkeen" for knife in Arabic came to our knowledge that day; before that, we used to call it "madiyah."
