3932. It was narrated that Safinah said: "I was a slave belonging to Umm Salamah. She said: 'I will manumit you, but I stipulate that you should serve the Messenger of Allāh ﷺ for as long as you live.' I said: 'Even if you do not stipulate such a condition, I shall not leave the Messenger of Allāh ﷺ as long as I live.' So she manumitted me and stipulated that condition for me." (Hasan)
