The Holy Quran:"And I have not created the Jinn and the men but that they may worship Me". (51:57) . "Surely, the first house founded for mankind is that at Becca (Mecca), abounding in blessings and guidance for peoples". (3:97). "He alone can maintain the Mosques of Allah who believes in Allah, and the last day, and observes prayer and pays the Zakat and fears none but Allah; so these it is who may be rightly guided." (9:18) The Holy Prophet on the importance of mosques O ye people, praise Allah. Whoever builds a mosque for Allah, Allah, The Exalted, shall build a house for such a one in paradise. The Promised Messiah said:"If you want Islam to progress build a mosque. Wherever our Jamaat is established, a mosque should be built. Our Jama'ats progress is founded on the construction of mosques. If there are only a few Muslims in a village or a city, build a mosque with good intentions and God will bring more Muslims to that place. It is not mandatory that the mosque be embellished or be a brick building. Wall off a piece of land and build a room with a thatched roof..." (Malfoozat Vol 2, p. 42)
