Bahá’í Sacred Writings, Bahá’u’lláh, #176

O people of the world! Build ye houses of worship throughout the lands in the name of Him Who is the Lord of all religions. Make them as perfect as is possible in the world of being, and adorn them with that which befitteth them, not with images and effigies. Then, with radiance and joy, celebrate therein the praise of your Lord, the Most Compassionate. Verily, by His remembrance the eye is cheered and the heart is filled with light….

Blessed is he who, at the hour of dawn, centring his thoughts on God, occupied with His remembrance, and supplicating His forgiveness, directeth his steps to the Mas̱hriqu’l-Aḏhkár and, entering therein, seateth himself in silence to listen to the verses of God, the Sovereign, the Mighty, the All-Praised. Say: The Mas̱hriqu’l-Aḏhkár is each and every building which hath been erected in cities and villages for the celebration of My praise. Such is the name by which it hath been designated before the throne of glory, were ye of those who understand.
