Quran Chapter 2 Verse 147-150
For each [religious following] is a direction toward which it faces. So race to [all that is] good. Wherever you may be, Allah will bring you forth [for judgement] all together. Indeed, Allah is over all things competent.
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.
And from wherever you go out [for prayer], turn your face toward al-Masjid al-Haram. And wherever you [believers] may be, turn your faces toward it in order that the people will not have any argument against you, except for those of them who commit wrong; so fear them not but fear Me. And [it is] so I may complete My favor upon you and that you may be guided.
