The opening as it read in 2005

Umar ibn al-Khattab, al-Farooq (in Arabic , عمر بن الخطاب) (c. 581 - November , 644 ), sometimes referred to as Umar Farooq or just as Omar or Umar , was the second caliph of Islam ( 634 - 644 ). He is regarded by Sunnis as one of the first four Khulfa-e-Rashidun (in Persian and Urdu , خلفأے راشدین) (or "Rightly Guided Caliphs"). The Shi'a , however, regard him as an unprincipled usurper.1
