In 1193, the Nalanda University was sacked by Bakhtiyar Khalji, a Turk this event is seen by scholars as a late milestone in the decline of Buddhism in India. Khilji is said to have asked if there was a copy of the Koran at Nalanda before he sacked it. The Persian historian Minhaj-i-Siraj, in his chronicle the Tabaquat-I-Nasiri, reported that thousands of monks were burned alive and thousands beheaded as Khilji tried his best to uproot Buddhism and plant Islam by the sword;the burning of the library continued for several months and "smoke from the burning manuscripts hung for days like a dark pall over the low hills."
Ahir considers the Qdestruction of the temples, monasteries, centers of learning at Nalanda and northern India to be responsible for the demise of ancient Indian scientific thought in mathematics, astronomy, alchemy, and anatomy.
ඉන්න හාමුදුරුවෝ දාස් ගානක් මැරුවා...මරලා ඉවරවෙලා පොත් කියවන්න බලනකොට කිසිම දෙයක් තේරෙන්නෑළු මුන්ට
මොකද කියවන්න දන්න කවුරුත්(කිසිම ප්රාණියෙක් )ඉතුරු වෙලා නෑ ඔක්කෝම මරලා.. ඊට පස්සේ කරන්න දෙයක් නැති කමට පොත් ඔක්කෝම ගිනි තිව්වා..ලෝකේ තිබ්බ ලොකුම දැනුම් සම්භාරය
