“…In the second year after this arrangement Muhammad Bakhtyar brought an army from Behar towards Lakhnauti and arrived at the town of Nudiya, with a small force; Nudiya is now in ruins. Rai Lakhmia (Lakhminia) the governor of that town… fled thence to Kamran, and property and booty beyond computation fell into the hands of the Muslims, and Muhammad Bakhtyar having destroyed the places of worship and idol temples of the infidels founded Mosques and Monasteries and schools and caused a metropolis to be built called by his own name, which now has the name of Gaur.
There where was heard before
The clamour and uproar of the heathen,
Now there is heard resounding
The shout of ‘Allaho Akbar’.”

What It Means

This is a placeholder explanation generated by the low-overhead model. It interprets "“…In the second year after this arrangement Muhammad Bakhtyar brought an army from Behar towards Lakhnauti and arrived at the town of Nudiya, with a small force; Nudiya is now in ruins. Rai Lakhmia (Lakhminia) the governor of that town… fled thence to Kamran, and property and booty beyond computation fell into the hands of the Muslims, and Muhammad Bakhtyar having destroyed the places of worship and idol temples of the infidels founded Mosques and Monasteries and schools and caused a metropolis to be built called by his own name, which now has the name of Gaur.
There where was heard before
The clamour and uproar of the heathen,
Now there is heard resounding
The shout of ‘Allaho Akbar’.”" in the context of "About Ikhtiyaru’d-Din Muhammad Bakhtiyar Khalji (AD 1202-1206) Navadvipa (Bengal) Muntakhabu’t-Tawarikh, translated into English by George S.A. Ranking, Patna Reprint 1973, Vol. I, p. 82-83" to mean that wisdom is timeless.
