- 8. Fatan: (Pattan): “There was another rai in these parts …a Brahmin named Pandya Guru… his capital was Fatan, where there was a temple with an idol in it laden with jewels. The rai fled when the army of the Sultan arrived at Fatan… They then struck the idol with an iron hatchet, and opened its head. Although it was the very Qibla of the accursed infidels, it kissed the earth and filled the holy treasury” (Ashiqa).

- Longer quote: There was another rai in those parts, whose rule extended over sea and land, a Brahmin named Pandya Guru. He had many cities in his possession, and his capital was Fatan, where there was a temple with an idol in it laden with jewels' The rai, when the army of the Sultan arrived at Fatan, fled away, and what can an army do without its leader? The Musalmans in his service sought protection from the king's army, and they were made happy with the kind of reception they met. 500 elephants were taken. They then struck the idol with an iron hatchet, and opened its head. Although it was the very Kibla of the accursed gabrs, it kissed the earth and filled the holy treasury.

- 'In the year 696, six hundred and ninety-six, he sent an army for the conquest of Gujarat under the command of Ulugh Khan who became famous among the Gujaratis as Alp Khan and Nusrat Khan Jalesri. These Khans subjected Naharwala that is, Pattan and the whole of that dominion to plunder and pillage' They broke the idol of Somnat which was installed again after Sultan Mahmud Ghaznawi and sent riches, treasure, elephants, women and daughters of Raja Karan to the Sultan at Delhi....[Somnath (Gujarat) ]
'After conquest of Naharwala and expulsion of Raja Karan, Ulugh Khan occupied himself with the government. From that day, governors were appointed on this side on behalf of the Sultans of Dilhi. It is said that a lofty masjid called Masjid-i-Adinah (Friday Masjid) of marble stone which exists even today is built by him. It is popular among common folk that error is mostly committed in counting its many pillars. They relate that it was a temple which was converted into a masjid' Most of the relics and vestiges of magnificence and extension of the ancient prosperity of Pattan city are found in the shape of bricks and dried clay, which inform us about the truth of this statement, scattered nearly to a distance of three kurohs (one kuroh = 2 miles) from the present place of habitation. Remnants of towers of the ancient fortifications seen at some places are a proof of repeated changes and vicissitudes in population due to passage of times. Most of the ancient relics gradually became extinct. Marble stones, at the end of the rule of rajas, were brought from Ajmer for building temples in such a quantity that more than which is dug out from the earth even now. All the marble stones utilized in the city of Ahmedabad were (brought) from that place[Patan (Gujarat)]

- 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.... 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. ....

- In 1196 AD he (Aibak) advanced against Anahilwar Patan, the capital of Gujarat. Nizami writes that after Raja Karan was defeated and forced to flee, “fifty thousand infidels were despatched to hell by the sword” and “more than twenty thousand slaves, and cattle beyond all calculation fell into the hands of the victors”. The city was sacked, its temples demolished, and its palaces plundered.

- “And in the year AH 698 (AD 1298) he appointed Ulugh Khan to the command of a powerful army, to proceed into the country of Gujarat… Ulugh Khan carried off an idol from Nahrwala… and took it to Dihli where he caused it to be trampled under foot by the populace; then he pursued Rai Karan as far as Somnat, and a second time laid waste the idol temple of Somnat, and building a mosque there retraced his steps.”

- It is true that Mosque architecture in Gujarat only began in the 14th century. When Ala-al-Din Khalji conquered and annexed the country to the Delhi Sultanate in the later part of the 13th century, there still flourished a singularly beautiful indigenous style of architecture. The early monuments of Gujarat, notably at Patan (Anhilvada) tell the same story of the demolition of local temples and the reconstruction of their fragments.
