What do you think about this book??

[إبراهيم بن عمر الأغا]

A friend of mine who recently converted to Islam bought a book in the name of (the biography of great muhaddith sheikh Nasiruddin Al-Albani) by Abu Nasir Ibrahim Abdul Rauf & Abu Maryam Muslim Ameen. Printed and published by Darussalam.
Does anyone has any idea about this book or its authors?
Although I trust the publisher in general.
In others words, I don’t want the guy to read any mistreated or unjust biography that can lead to a negative overview!
Thanks all.. URGENT!
