Anas ibn Malik
Muhammad's father (the name Abu Bakr was seldom used) was one of the many captives taken by Khalid ibn al-Walid after the Battle of Ayn al-Tamr. He was a coppersmith from a town called Jirjaya (Gerzhiya) (Arabic: جرجرايا, south east of Baghdad), settled and working there, where a decisive battle took place in year 12. According to the "Encyclopedia of Islam" (London; Leiden &amp; E.J. Brill, 1971), vol. 3, p. 947, Ibn Sirin's mother, Safiyya – a servant of the caliph Abu Bakr – was held in such esteem within the community that when she died, her laying-out was performed by three of Muhammad's wives and eighteen "Badris" (veterans of the battle of Badr), led by Ubay ibn Ka'b, were present at her burial. 'Umar sent him as a present, either directly to Anas ibn Malik (one of the most authoritative sources on the life and opinions expressed by Muhammad) or first to a man called Talha Al-Bukhari (from Bukhara, Central Asia) who, in turn, gave him to Anas.
