What is the purpose of Hajj?
As one of the five pillars of Islam, the purpose of Hajj for Muslims means fulfilling our spiritual duties to Allah (SWT) and showing our submission to Him. Muslims believe Hajj offers a chance to wipe clean past sins and start anew before Allah. Additionally, the act of performing Hajj with increased Taqwa (being God-conscious) and to a high standard of perfection, is rewarded with Paradise.
