"However, when one reads what Sir Syed Ahmed Khan22 of Aligarh fame proudly wrote about the destruction of 2 7 temples, one's impression of Islam gets shaken. What he wrote is best read in his original words, (from his Urdu book, Asar-us-Sanadid, translated by Prof. Khaleeq Anjum, Delhi in 1990, Volume I): Quwwatal-Islam Masjid 'd Din Sam alias Shihabu 'd-Din Ghauri, conquered Delhi in AH 587 corresponding to AD 1191 corresponding to 1248 Bikarmi, this idol-house (of Rai Pithora) was converted into a mosque. The idol was taken out of the temple. Some of the images sculptured on walls or doors or pillars were effaced completely, some were defaced. But the structure of the idol-house kept standing as before. Material from twenty-seven temples, which were worth five crore and forty lakh of Dilwals, were used in the mosque, and an inscription giving the date of conquest and his own name was installed on the eastern gate. When Malwah and Ujjain were conquered by Sultan Shamsu 'd-Din in AH 631 corresponding to AD 1233, then the idol-house ofMahakal was demolished and its idols as well as the statues of Raja Bikramajit were brought to Delhi, they were strewn in front of the door of the mosque."
