"Of the mosques of Alauddin Khalji constructed outside the capital, mention may be made of the masjid at Mathura and the tomb of Shaikh Farid (built C 1300), which was probably a converted Hindu or Jain temple. There is another masjid built about the same time in Bharuch. it is also a converted Jain temple. In 1300 Alp Khan, brother-in-law of Alauddin and governor of Gujarat, constructed the Adinah mosque at Patan. It was built of white marble, and it is related "that it was once an idol temple converted into a mosque". The Adinah mosque no longer exists. After the conquest of Chittor in 1303, Alladin "constructed a congregational mosque. There was a temple lying in ruins." In Biana there is the Ukha mosque belonging to the Khalji period. Many mosques were built during Alauddin's invasion of the South. Farishtah claims that a mosque was built as far away as at Rameshwaram and called Masid-i-Alai and that it was in existence when Farishtah lived.137 The above examples clearly show that as per the dictates of the Quran and the injunctions of the Hadis and the Sunnah, mosques in India too were built on the sites of the idol temples and with the materials obtained from razing the shrines. ...."
