who constructed the mosque called dhai din ka jhopra
Adhai Din Ka Jhonpra The original building was partially destroyed and converted into a mosque by Qutb-ud-Din-Aibak of Delhi in the late 12th century. According to a local legend, after defeating Vigraharaja's nephew Prithviraja III in the Second Battle of Tarain, Muhammad Ghori passed through Ajmer. There, he saw the magnificent temples, and ordered his slave general Qutb-ud-Din-Aibak to destroy them, and construct a mosque – all within 60 hours (that is, ​2 1⁄2 days). The artisans could not build a complete mosque in 60 hours time, but constructed a brick screen wall where Ghori could offer prayers. By the end of the century, a complete mosque was built.[1]
Jama Masjid, Delhi It was built by Mughal emperor Shah Jahan between 1644 and 1656 at a cost of 1 million rupees, and was inaugurated by an imam from Bukhara, present-day Uzbekistan. The mosque was completed in 1656 AD with three great gates, four towers and two 40 m high minarets constructed of strips of red sandstone and white marble. The courtyard can accommodate more than 25,000 persons. There are three domes on the terrace which are surrounded by the two minarets. On the floor, a total of 899 black borders are marked for worshippers. The architectural plan of Badshahi Masjid, built by Shah Jahan's son Aurangzeb at Lahore, Pakistan, is similar to the Jama Masjid, Delhi.
