Ibn ’Abbas (RAA) narrated that Allah’s Messenger (ﷺ) said: “When a man’s slave-woman bears him a child she becomes free at his death.” Related by Ibn Majah and Al-Hakim with a weak chain of narrators. A group of Hadith scholars held that the stronger view is that it is Mawquf (a saying of a Companion) i.e. 'Umar (ra).
