Umar bin Abdul Aziz
By Abu Tariq Hijazi | 07 Sept 2012
There are a few rulers in the world who have left indelible impressions in history. Caliph Umar bin Abdul Aziz tops that list. He is considered one of the finest rulers in Muslim history, second only to the four rightly guided caliphs — Abu Bakr, Umar, Uthman and Ali (RA). In fact, in some circles, he is affectionately referred to as the fifth and the last caliph of Islam.
