Qutb was a fanatical Muslim. When his garrison occupied Delhi under the command of Muhammed Ghori in 1192, he ordered the destruction of twenty-seven Hindu and Jain temples to furnish building materials for the construction of Delhi's first mosque. Quwwat-ul-Islam, the "Glory of Islam," was hastily erected by the young amir, who conscripted an army of local craftsmen, presumably Hindus, to assemble the structure. The Hindu stonemasons repurposed columns from the destroyed temples, but adapting them to use in a mosque proved problematic given Islam's injunction against the use of images in temples. The masons were forced to plaster over the highly sculpted Hindu columns and presumably cover them with geometric designs. However, after centuries of neglect the plaster has fallen away, revealing the original Hindu carvings.
