It is not Al-Birr (righteousness) that you turn your faces towards the East or West (in prayers); but Al-Birr is (the quality of) the one who believes in Allah, the Last Day, the Angels, the Book, the Prophets and gives his wealth, in spite of his love for it, to the kinsfolk, to the orphans, to the poor, to the wayfarer, and to those who ask, and sets slaves free and performs As-Salat, and gives Zakat, and fulfils a covenant when he makes it, and is patient in extreme poverty and ailment and at the time of fighting. Such are the people of the truth and they are Al-Muttaqun (pious).

[Surat Al-Baqarah:177]
