“[A] forthright and entertaining treatise . . . Moghul’s candid mix of devotional and memoir make this a solid primer on Islam.” - Publishers Weekly
“This is a book that only Haroon Moghul could write. It is honest and hopeful, beautiful and painful, visionary and personal. It is at once a history of Islam and a guidebook to your soul. There are paragraphs so perfect, I read them aloud to family and friends.” - Eboo Patel
“In his stunning new Two Billion Caliphs, Haroon Moghul describes the Hagar of sacred text as representing ‘a kind of ambling Islam.’ In that same spirit, Moghul’s work ambles and careens across time, space, theology, and intimate self-discovery, to locate a new take on Islam. Moghul’s vision of a collective, personal, loving, and meaningful faith - born of his own frailty, curiosity, and longing - requires nothing less than the opening of a spiritual vein. What emerges is honest and transformational and desperately needed, in all of our conversations around religion.” - Dahlia Lithwick, senior editor, Slate
“In this touching, moving, and thought-provoking book, Haroon Moghul boldly proclaims, and elegantly articulates, the big paradigm shift desperately needed in Islamic thinking: Muslims should let go of the political ‘caliphate,’ with all its religious rigidity, fury, and oppressiveness. Instead, they should revive the original Quranic ‘caliphate’: the wisdom and moral agency within the heart of every human being. I cannot applaud him more.” - Mustafa Akyol, senior fellow on Islam and modernity at the Cato Institute, author of Reopening Muslim Minds: A Return to Reason, Freedom, and Tolerance
