It was narrated that 'Aishah said: Ibn Zam'ah and Sa'd (Ibn Abu Waqqas) referred a dispute to the Prophet P.B.U.H concerning the son of Zam'ah's slave woman. Sad said: "0 Messenger of Allah, my brother (Utbah bin Abu Waqqas) left instructions in his will that when I come to Makkah, I should look for the son of the slave woman of Zam'ah and take him into my care." 'Abd bin Zam' ah said: "He is my brother and the son of the slave woman of my father; he was born on my father's bed." The Prophet P.B.U.H saw that he resembled 'Utbah, and said: "He belongs to you, 0 'Abd bin Zam'ah, The child is for the bed. Observe Hijab before him, 0 Saudah." (Sahih)
