"The British Museum and the Victoria and Albert Museum, both in London, the Indian Museum and the Bangiya Sahitya Parishad Museum, both at Calcutta, Varendra Research Society Museum, Rajshahi, provide large specimens of carved stones and architectural fragments used in the monuments of pre-Mughal Bengal. Ravenshaw photographed a circular stone pedestal and a gargoyle, which is now in the Indian Museum, Calcutta. Used obviously as the gargoyle in the Adina Masjid, it ‘consists of a modification of an elephant’s head with the eyes, horns and ears of a sardula (elephant).’ Cunningham found in the pulpit of the Adina Masjid ‘a line of Hindu sculpture of very fine bold execution.’ Innumerable Hindu lintels, pillars, door-jambs, bases, capitals, friezes, fragments of stone carvings, dadoes, etc., have been utilized in such a makeshift style as to render ‘improvisation’ well-nigh impossible. In many cases as observed in the Quwwat al-Islam at Delhi and the Arhai-din-ka-Jhopra Mosque at Ajmer, pillars were inverted, joining the base with capitals, suiting neither pattern nor size. Still there is no denying the fact that Hindu materials were utilized, yet it would be far-fetched to say that existing Hindu temples were dismantled and converted by improvisation into mosques as observed in the early phase of Muslim architecture in Indo-Pak sub-continent. The ritual needs and structural properties of the Hindus and the Muslims are so diametrically opposite as to deter any compromise and, therefore, the early Muslim conquerors of Bengal said their prayer in mosques built out of the fragments of Hindu materials in the same way as their predecessors did at Delhi, Ajmer, Patan, Janupur, Dhar and Mandu, and elsewhere. In the event [absence?] of any complete picture of pre-Muslim Hindu art as practised in Gaud and Hazrat Pandua, it is an exaggeration to hold the view after Saraswati that ‘indeed, every structure of this royal city (Hazrat Pandua) discloses Hindu materials in its composition, thus, disclosing that no earlier monument was spared.”"
