Allah said: And Hajj (pilgrimage to Makkah) to the House (Kabah) is a duty that mankind owes to Allah (Glory be to Him), those who can afford the expenses (for ones conveyance, provision and residence); and whoever disbelieves (i.e. denies Hajj (pilgrimage to Makkah), then he is a disbeliever of Allah), then Allah stands not in need of any of the Alameen (mankind and Jinns).
