Hadith.3461 - It is narrated from al-Ala', from Muhammad ibn Muslim, from one of the Imams , peace be upon them, who said: "A mudabbar (a slave promised freedom after the owner's death) is considered to be from the one-third (of the estate). A man has the right to retract from his bequest regarding this one-third, whether he made the will during his health or illness."
