“The book overall is an exceptional contribution to the literature on Islamic finance and to the credit of Masood, his book is among the new generation of works in the field that are scientifically grounded. The author is to be applauded for this book, which provides a basic manual for anyone interested to learn or advance in this field.” (Ilias Bantekas, Manchester Journal of Transnational Islamic Law & Practice, Vol. 16 (1), 2020)
