My question is that was Malik Bin Dinar a Sahabi or Tabeyi? Please give me detailed information related to this person. Also tell me which book should I consult regarding the biographies of Sahabas or Tabiyin?
بسم الله الرحمن الرحيم
(1) Yes, Malik Ibn Dinar was a Tabiye, not a Sahabi.
(2) In order to know the history of Sahaba and Tabiyeen you should study the books: Seeratut Tabiyeen, Siyarus Sahaba, Siyarus Sahabiyat and Hayatus Sahaba etc.
Allah knows Best!
