Islamika samooham sangraha charithram - Volume 1

Last 2 weeks I spent time to read "Islamika samooham sangraha charithram - Volume 1" by a Pakistani Author Sarwat Soulat and translated by Abdurahman Munnoor. This book gives glimpses of history of muslim rulers and famous personalities. This is more of history of caliphs and sultans from Hijra 1 to Hijra ~650. The author briefly goes over the dynasties of Khalifa, ummayyad, abbaside, fathimide, saljook, ghasni, ghori, sanki, ayyoobi, barbar (muvahhid), etc. Its not a neutral book and all along we can see author is muslim-sided and apolegetic. Also he has mentioned one or two incidents for each of the famous personalities otherwise its a kind of text book. It is not meant for serious readers since the citation is too less. May be its good to get a blur picture of that time-frame. But I appreciate author's commitment to cover all major rulers and personalities of that time. That way this book is good to use as a reference.
