At Hajj, we Muslims must walk 7 times between the hills of Safa and Marwa and at some point many touch the water from the well of Zam-Zam. Why? Because only in following the footsteps of Hajra do Muslims complete the Hajj. Who was Hajra? She was the founder of Mecca. Yes -- a woman founded Mecca. Islam has a matriarch. And not only was she a woman. She was a slave.
