Masjid al-Haram
According to Muslims, Abraham was ordered by Allah to construct the Kaaba at the place where Adam had previously built it. He, along with his son Ishmael, rebuilt the Kaaba. As they laid the bricks, Abraham realized that the walls of the Kaaba were too high for him to reach. So, he took a large rock and stood over it. As the wall gets higher, the rock also miraculously grows bigger to allow Abraham to reach the top of the walls. The rock, with the footprint of Abraham, is the "Maqam Ibrahim". After they have finished building, Allah sent down a white-colored stone from the Paradise down to Earth. The stone was placed on the corner of the Kaaba. This white stone became black because of the sins of the people that touched it. This stone is known as the "Hajar al-Aswad", which means "Black Stone".
