It is narrated from Sulayman bin Yasar that a Saibah (a slave woman freed by someone performing Hajj) killed the son of a man who was from Banu Aidh. The father of the slain came to Sayyiduna Umar (may Allah be pleased with him) to claim the blood money for his son. Sayyiduna Umar (may Allah be pleased with him) said: There is no blood money for him. The man said: If my son had killed the Saibah, what would you have ruled? Sayyiduna Umar (may Allah be pleased with him) said: Then you would have had to pay her blood money. The man said: Then what is a Saibah? She is like a spotted snake; if you let her go, she bites, and if you kill her, she takes revenge.
