وَمِنْ حَيْثُ خَرَجْتَ فَوَلِّ وَجْهَكَ شَطْرَ الْمَسْجِدِ الْحَرَامِ ۖ وَإِنَّهُ لَلْحَقُّ مِن رَّبِّكَ ۗ وَمَا اللَّهُ بِغَافِلٍ عَمَّا تَعْمَلُونَ (149)
(2:149) At whatever place you may be, turn your face towards Masjid Haram (at Prayer time) for this is, in fact, a Commandment of your Lord, and Allah is not unaware of what you do.
