that 'Umar bin Al-Khattab said: "O Messenger of Allah (ﷺ)! I wish that we could perform Salat behind the Maqam: So the following was revealed: And take you the Maqam of Ibrahim as a place of Salat. (2:125)."
Jami` at-Tirmidhi Book 47, Hadith 11
← Previous Hadith "The Messenger of Allah (ﷺ) would perform voluntary Salat upon his mount facing whichever direction he was headed, while he was coming from Makkah to Al-Madinah." Then Ibn 'Umar recited: To Allah belong both the east and the west. (2:115)"

And Ibn 'Umar said: "It was about this that the Ayah was revealed."

This Hadith is Hasan Sahih.

It has been reported from Qatadah that he said about this Ayah: To Allah belong both the east and the west, so wherever you turn, there is the Face of Allah. : So turn your face in the direction of Al-Masjid Al-Haram. Meaning: facing it."

And it has been reported that Mujãhid said about this Ayah: "So wherever you turn, there is the Face of Allah": "So there is the direction of Allah."
