Musannaf Ibn Abi Shaybah 29750 — Blood cases decided by rulers

Nafi' said that Sayyiduna Ibn Umar (may Allah be pleased with them both) said: A slave girl of Sayyidah Hafsah (may Allah be pleased with her) cast a spell on her, and they also perceived the effect of the sorcery, and the slave girl confessed to it. So Sayyidah Hafsah ordered Abd al-Rahman bin Zayd, and he killed her. The news reached Sayyiduna Uthman (may Allah be pleased with him), and he disapproved of this and was very angry about it. Sayyiduna Ibn Umar (may Allah be pleased with them both) came to him and informed him that this slave girl had cast a spell on Sayyidah Hafsah and had also confessed to it, and that they had also found the effect of her sorcery. So it was as though Sayyiduna Uthman disapproved of it because she had been killed without his permission.
