Al-Farūq (Urdu: الفاروق) is a biography of Caliph Umar, written by Shibli Nomani.

Umar is universally acknowledged as the first conqueror, founder and administrator of the Muslim Empire.

By extensive study of the subject, the author Nomani collected and collated facts which were lying buried in unpublished manuscripts in great libraries of Istanbul, Beirut, Alexandria, Paris, Berlin and London.

The book inspired an unparalleled enthusiasm and ran into several editions in a very short period.

The book was translated into English by Maulana Zafar Ali Khan and was titled, Al Farooq: The Life of Omar The Great (Second Caliph of Islam).
