The primary chronicle of Muhammad Ghori's campaigns in India and the early Delhi Sultanate, written by Hasan Nizami, a poet attached to the Ghurid court. It documents in detail the sack of Delhi, the destruction of temples, the building of the Quwwat-ul-Islam mosque on 27 demolished temples, the destruction of Ajmer's Sanskrit college, and the sack of Varanasi where "a thousand temples were emptied." This is the single most important primary source for Ghori's Indian campaigns.

A comprehensive Islamic history of dynasties from the Prophet to the early Delhi Sultanate, written by the chief judge (qadi) of Delhi under the Sultanate. Contains the primary account of the burning of Nalanda ("the smoke darkened the air for three months"), detailed accounts of both Battles of Tarain, the capture and execution of Prithviraj Chauhan, and Bakhtiyar Khilji's Bihar campaigns. One of the most widely cited medieval sources on this period.

A comprehensive history of Muslim rule in India from the Arab invasion through the Mughal period. Ferishta drew extensively on earlier sources including the Taj-ul-Maasir and Tabaqat-i-Nasiri, and added additional details and context. His accounts of the Battles of Tarain, the establishment of the Delhi Sultanate, and the Gujarat campaign are particularly useful for cross-referencing.

The epic poem of the bard Chand Bardai, court poet of Prithviraj Chauhan, documenting the battles of Tarain from the Indian perspective. While scholars debate its complete historical accuracy (parts were likely added later), it provides valuable information about the Rajput perspective on the Tarain battles, including the account of Prithviraj's capture and Ghori's wounding in the first battle.

The early accounts of Ghori's Multan campaigns and Gujarat defeat are documented in fragments of contemporary chronicles and later histories that draw on earlier sources. The Gujarat defeat at Kasahrada is described in both Ferishta and earlier chronicle fragments.

ASI excavations of the Nalanda site have confirmed massive fire damage consistent with medieval chronicle accounts. The library building layers show evidence of catastrophic burning.

The Quwwat-ul-Islam mosque contains columns with visible Hindu and Jain carvings — bells, chains, garlands, and deity faces — from the demolished temples. The mosque's own foundational inscription (still legible) records that it was built from materials of demolished temples.

Archaeological Survey of India excavations at Antichak village in Bihar have identified the ruins of Vikramashila University with evidence of destruction by fire consistent with the historical accounts of Bakhtiyar Khilji's campaign.

The mosque in Ajmer, built on the demolished Sanskrit college, still has original Sanskrit inscriptions on its interior walls. These are visible to visitors today and confirm the site's pre-Islamic use. The name of the original Sanskrit college is preserved in these inscriptions.
