al-Isabah fi tamyiz-is-sahabah – Ibn Hajr Asqalani, Publish: Dar al-Kutub al-Azhar, Misr
The biographical sketch provided by Ibn Hajar ‘Asqalani: “Malik bin ‘Iyad, a slave freed by ‘Umar, was known as Malik ad-Dar. He had seen the Holy Prophet (Peace Be Uopn Him) and heard traditions from Abu Bakr. He has taken traditions from Abu Bakr as-Siddiq ‘Umar Faruq , Mu‘adh and Abu ‘Ubaydah, and Abu Samman and the two sons of this (Malik ad-Dar) ‘Awn and ‘Abdullah have taken traditions from him. “And Imam Bukhari in at-Tarikh-ul-kabir, (7:304-5), through reference to Abu Salih, has acknowledged a tradition from him that ‘Umar is reported to have said during the period of famine: I do not shirk responsibility but I may be made more humble.
Ibn Abu Khaythamah has reproduced a long tradition along with these words (which we are discussing), … and I have copied a tradition narrated by ‘Abd-ur-Rahman bin Sa‘id bin Yarbu‘ Makhzumi with reference to Malik ad-Dar, in Fawa’id Dawud bin ‘Umar and ad-Dabi compiled by Baghawi. He said that one day ‘Umar called me. He had a gold wallet in his hand, which had four hundred dinars in it. He commanded me to take it to Abu ‘Ubaydah, and then he narrated the remaining part of the happening. Ibn Sa‘d has placed Malik ad-Dar in the first group of Successors among the natives of Medina and has averred that he has taken traditions from Abu Bakr as-Siddiq and ‘Umar, and he was known. Abu ‘Ubaydah has asserted that ‘Umar had appointed him the guardian of his family. When ‘Uthman was elevated to the office of the caliph, he appointed him as the minister of finance, and that is how he came to be known as Malik ad-Dar (the master of the house).
