Kitáb-i-Aqdas

Question: The believers have been enjoined to face in the direction of the Qiblih when reciting their Obligatory Prayers; in what direction should they turn when offering other prayers and devotions?

Answer: Facing in the direction of the Qiblih is a fixed requirement for the recitation of obligatory prayer, but for other prayers and devotions one may follow what the merciful Lord hath revealed in the Qur'án: "Whichever way ye turn, there is the face of God."
