Sura al-Baqara 2:149

وَمِنْ حَيْثُ خَرَجْتَ فَوَلِّ وَجْهَكَ شَطْرَ ٱلْمَسْجِدِ ٱلْحَرَامِ وَإِنَّهُۥ لَلْحَقُّ مِن رَّبِّكَ وَمَا ٱللَّـهُ بِغَٰفِلٍ عَمَّا تَعْمَلُونَ

wa-min ḥaythu kharajta fa-walli wajhaka shaṭra l-masjidi l-ḥarāmi wa-innahu lal-ḥaqqu min rabbika wa-mā allāhu bi-ghāfilin ʿammā taʿmalūna

From whencesoever Thou startest forth, turn Thy face in the direction of the sacred Mosque; that is indeed the truth from the Lord. And Allah is not unmindful of what ye do.
