2:149
وَمِنْ حَيْثُ خَرَجْتَ فَوَلِّ وَجْهَكَ شَطْرَ ٱلْمَسْجِدِ ٱلْحَرَامِ ۖ وَإِنَّهُۥ لَلْحَقُّ مِن رَّبِّكَ ۗ وَمَا ٱللَّهُ بِغَـٰفِلٍ عَمَّا تَعْمَلُونَ ١٤٩

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