Al-Baqarah 2:149

Wamin haythu kharajta fawalliwajhaka shatra almasjidi alharami wa-innahulalhaqqu min rabbika wama Allahu bighafilinAAamma taAAmaloon

So from wherever you go out [for prayer, O Muḥammad], turn your face toward al-Masjid al-Ḥarām, and indeed, it is the truth from your Lord. And Allāh is not unaware of what you do.

From wherever you set out, turn your face in the direction of the Sacred Mosque (Al-Masjid-ul-Harām). That, indeed, is the truth from your Lord, and Allah is not unaware of what you do.
