Task: Question Generation
Input (English): A Turco-Mongol conqueror in Central Asia, Timur (Tamerlane), attacked the reigning Sultan Nasir-u Din Mehmud of the Tughlaq Dynasty in the north Indian city of Delhi. The Sultan's army was defeated on 17 December 1398. Timur entered Delhi and the city was sacked, destroyed, and left in ruins, after Timur's army had killed and plundered for three days and nights. He ordered the whole city to be sacked except for the sayyids, scholars, and the "other Muslims" (artists); 100,000 war prisoners were put to death in one day. The Sultanate suffered significantly from the sacking of Delhi revived briefly under the Lodi Dynasty, but it was a shadow of the former.
Output (English): What were exempted from death by Timur when ordering Delhi sacked?
