Abu Qubays (Arabic: جَبَل أَبُو قُبَيْس \ جَبَل أَبِي قُبَيْس, romanized: Jabal Abū Qubays / Jabal Abī Qubays) is a sacred mountain which resides on the eastern frontier of Al-Masjid Al-Haram in Mecca,[1] in the Hejaz region of Saudi Arabia.

Although the exact origin of its name is unknown, it is believed to be called Al-Amīn (ٱلْأَمِيْن) in pagan times because the sacred Black Stone resided there according to Muslims[who?].

According to another report, this mountain was also called the Maghārat al-Kanz (مَغَارَة ٱلْكَنْز, "Treasure Cave"), and this was believed to be the place where the first of men stayed and were buried after their death.

According to tradition, this is the place where the Islamic Prophet Muhammad performed the miracle of splitting the Moon into two pieces and then re-attaching those pieces as demanded by the disbelievers of Makkah.
