To where does the qibla of Quba Mosque point?

The direction of the qibla (definition) for Quba Mosque, and all mosques of Muslims, points towards the Sacred House in Mecca, as Allah Almighty says: "We have certainly seen the turning of your face, [O Muhammad], toward the heaven. And We will surely turn you to a qiblah with which you will be pleased. So turn your face toward the Sacred Mosque. And wherever you [believers] are, turn your faces toward it [in prayer]. Indeed, those who have been given the Scripture well know that it is the truth from their Lord. And Allah is not unaware of what they do." (Al-Baqarah: 144).
