Divination and Omens (Kitab Al-Kahanah Wa Al-Tatayyur)

Dawud :: Book 29 : Hadith 3921

Narrated Umm Salamah, Ummul Mu'minin:

Safinah said: I was a slave of Umm Salamah, and she said: I shall emancipate you, but I stipulate that you must serve the Apostle of Allah (peace_be_upon_him) as long as you live. I said: Even if you do not make a stipulation, I shall not leave the Apostle of Allah (peace_be_upon_him). She then emancipated me and made the stipulation with me.
