It had long been Hazrat Mirza’s wish that a small cubicle should be constructed adjacent to the Bait-ul-Fikr (House of Contemplation) solely for the purposes of offering prayer. Hazrat Mirza desired the cubicle to be so compact that not even a bed should fit in it so that it could only be used for worship and prayers.
Accordingly, the Bait-ud-Dua (House of Prayer) was constructed during Marchof 1903. All related expenses were borne by Sheikh Rahmatullah, the proprietor of Bombay House, Lahore.1
