وَمِنْ حَيْثُ خَرَجْتَ فَوَلِّ وَجْهَكَ شَطْرَ الْمَسْجِدِ الْحَرَامِ ۖ وَإِنَّهُ لَلْحَقُّ مِن رَّبِّكَ ۗ وَمَا اللَّـهُ بِغَافِلٍ عَمَّا تَعْمَلُونَ
"And from wheresoever you start forth (for prayers), turn your face in the direction of Al-Masjid-al-Haram (at Makkah), that is indeed the truth from your Lord. And Allah is not unaware of what you do." (Quran 2:149)
