In The Name of Allaah, The Most Merciful, The Bestower of Mercy

Imaam Albaani (rahimahullaah) stated that the one who authored this Book (i.e. Hayatus Sahaabah) is not merely an individual amongst Jamaat At-Tableegh, but he is a figurehead, if not a figurehead of the figureheads. He authored this book and the Jamaa’ah (At-Tableegh) apply what it guides to; but this book is compiled in a haphazard manner; meaning: The author did not distinguish what is in this book with a mention- first and foremost- of what is narrated from the Messenger (sallal-laahu-alayhi-wasallam) with authentic chains of transmission; because the speech of the Messenger is not like the speech of others even if they (i.e. others) are from the righteous friends of Allaah.

Secondly: The author mentioned many narrations attributed to the Sahaabah (radiyallaahu-anhum); and when it is the case that he did attribute unauthentic narrations to the Prophet (sallal-laahu-alayhi-wasallam), which the people of knowledge do not consider to be authentic based on the science of Hadeeth,  its chains of transmissions and the biographies of the narrators, then it is most likely that he would mention numerous unauthentic narrations attributed to the actions, methodology and manners of the Sahaabah.  Paraphrased…see full discussion here: Imaam_Albaanee

Then Imaam Albaanee (rahimahullaah) mentioned a very important statement of Shaykhul Islaam Ibn Taymiyyah (rahimahullaah) as follows:

على كل باحث أن يتثبت فيما يرويه عن أصحاب النبي، كما يتثبت فيما يرويه عن الله ورسوله [Every researcher in the affairs of knowledge of the sharia must ascertain what he narrates about the companions of the Prophet (i.e. such narrations must have an authentic chain of transmission and the correct understanding of them), just as the researcher is (required) to ascertain whatever he narrates about Allaah and His Messenger (i.e. anything he attributes to Allaah and Messenger must be established from the Qur’aan and authentic Sunnah, obviously accompanied by the understanding of the Salaf).  [Listen to audio here:
