Shamsuddin Iltutmish who succeeded Aibak at Delhi invaded Malwa in 1234 AD. He destroyed an ancient temple at Vidisha. Badauni reports: “Having destr… - Iltutmish

“In AH 631 he invaded Malwah, and after suppressing the rebels of that place, he destroyed that idol-temple which had existed there for the past three hundred years.... “Next he turned towards Ujjain and conquered it, and after demolishing the idol-temple of Mahakal, he uprooted the statue of Bikramajit together with all other statues and images which were placed on pedestals, and brought them to the capital where they were laid before the Jami‘ Masjid for being trodden under foot by the people.”110

Naqvi has taken pains to describe at length the edifice which began as a temple, got converted into a tomb and to which was added a masjid with a marble mehrab and then a gate with pretty Arabic calligraphy of verses from the Holy Quran. As he puts it, the gateway projects 13 ~feet from the enclosure wall and is approached and entered by a flight of steps flanked by two square rooms which are roofed with stone slabs in the Hindu fashion. The external archway of the gate is formed by overlapping courses of marble and around it is the important Arabic inscription in Kufic characters.
He goes on, after crossing the threshold, one stands under the eastern colonnaded verandah, the flat roof of which rests on red sandstone pillars. The latter are not uniformly carved, indicating that they have been re-used here from an older building. Opposite this colonnade and along the whole length of the west em wall runs another colonnaded verandah with a prayer chamber in the centre erected in white marble and covered with a corbelled pyramidal dome. The dome is almost certainly re-used and is lavishly carved internally with Hindu motifs, notably bands of lozenge or triangular patterns. The marble mehrab is embellished with verses from the Quran and a floral design. The floor is paved with marble slabs. The rest of the verandah on either side of the prayer chamber comprises red sandstone pillars and pilasters supporting a flat roof of Hindu design, with a brick work parapet...
He winds up his description with the words: The Hindu elements in the architecture of the monument are apparent in the dome of the mosque and the partly defaced Hindu motifs on some of the pillar brackets of the western colonnade. The presence of a Gauripatta or receptacle of a linga in the pavement of the western colonnade is a further significant point. Furthermore, the marble stones in the external facade of the mosque are serially numbered, indicating their removal from elsewhere.

After he had reached the capital he sent, in A.H. 632 (1234 A.D.), the army of Islam towards Malwa and took the fort and city of Bhilsa. There was a temple there which was three hundred years in building. It was about one hundred and five gaz high. He demolished it. From thence he proceeded to Ujjain, where there was a temple of Maha-kal, which he destroyed.
