2:149And whencesoever thou comest forth (for prayer, O Muhammad) turn thy face toward the Inviolable Place of Worship. Lo! it is the Truth from thy Lord. Allah is not unaware of what ye do.
وَمِنْ حَيْثُ خَرَجْتَ فَوَلِّ وَجْهَكَ شَطْرَ الْمَسْجِدِ الْحَرَامِ وَإِنَّهُ لَلْحَقُّ مِنْ رَبِّكَ وَمَا اللَّهُ بِغَافِلٍ عَمَّا تَعْمَلُونَ
