Once in a lifetime, Hajj and ‘Umrah are decreed for those who can afford it. Pilgrimage commemorates Abraham’s exemplary submission to God (Appendix 9), and must be observed during the four Sacred Months—Zul-Hijjah, Muharram, Safar, & Rabi’ I (12th, 1st, 2nd, 3rd months) (2:197; 9:2, 36). ‘Umrah can be observed any time. Like all other duties in Islam, Hajj has been distorted. Most Muslims observe Hajj only during a few days in Zul-Hijjah, and they consider Rajab, Zul-Qi’dah, Zul-Hijjah, and Muharram (7th, 11th, 12th, 1st months) to be the Sacred Months. This is a distortion that is strongly condemned (9:37).
