للشيخ أحمد بن مبارك بن قذلان المزروعي
Here is an excellent book entitled "The Efforts of the Mâliki Scholars to Demonstrate the Rights of Leaders and Their Position towards astray Groups."
We find in this book the belief of the Mâliki scholars on subjects related to the imâmah (the governorate), such as: the concept of the imâmah, how it contracts, the conditions of the governor, his obligations, his rights, their position towards the caliphate of the 4 caliphs and those who followed them, and their position towards the misguided groups on this subject such as the khawâreej, the mou'tazilah and the chi'ah.
In 2 volumes, this book is basically a master's thesis written by a Sheikh Salafi from the United Arab Emirates.
2 volumes, yellow pages, 17x24 cm format, hardcover, دار أضواء السلف edition.
