وَمِن حَيثُ خَرَجتَ فَوَلِّ وَجهَكَ شَطرَ المَسجِدِ الحَرامِ ۖ وَإِنَّهُ لَلحَقُّ مِن رَبِّكَ ۗ وَمَا اللَّهُ بِغافِلٍ عَمّا تَعمَلونَ

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.
