Muslims believe that Kaaba(granite, 13 metres building), holiest place on Earth, was built by Abraham and Ishmael along with the god’s commands. Haj mission brings Muslims all together regardless of their nationalities, genders, financial situations, political power, etc. under the command of god.
Men wear two pieces of white fabric and women wear one piece, only face and hands free. Anything fancy is forbidden and of course no make-up. They kinda pre-perform the Judgement Day. No one differs from the other at all.
They are all willing to receive the god’s contentment. One way to do that is to obey the rules delivered by his prophet and avoid his prohibitions. His rules are for leading us to goodness and prohibitions are for keeping us away from evil. So he keeps us clean and well-moral.
