The Jabal Abu Qubais or the mountain of Abu Qubais is located just opposite the Holy Kaaba close to the Mountain Safa. Many Islamic events are attached to the mountain.
It is located adjacent to the mount safa. It is believed that this was the mount from where Prophet (PBUH) pointed towards the moon and split into two.
Omar Mahmood writes in his book Muhammad, an Evolution of God that very first mountain created by Allah Almighty is Mountain Abu Qubais.
When Prophet Adam A.S given the task to build the Holy Kaaba, he took rocks from the very mountain. So the Holy Kaaba built on earth for the first time used foundation rocks from the mount of Abu Qubais.
Allamah Muhammad Baqir Al-Majlisi writes in his book Hayat Al Qulub, Vol. 1, Stories of the Prophets that Prophet Ibrahim A.S stood on the mountain Abu Qubais and asked people to believe in Allah and worship no one but Allah
The disbelievers asked Prophet ﷺ to split the moon into two halves , only then they would put faith in Allah Almighty. It is said that the Prophet ﷺ either stood on or by the mount Abu Qubais and asked Allah Almighty to grant the miracle.
