Who among the following came to India at the instance of Sultan Mahmud of Ghazni?
A
AI-Masudi
B
Al-Biruni
C
Sulaiman
D
Abdul Haq
Correct Answer: Al-Biruni
Sultan Mahmud of Ghazni, while seated in his four-domed summer house in the garden of a thousand trees, requested Al-Biruni to forecast, by his knowledge of the stars, which door the Sultan would leave the building. When Al-Biruni had complied with this command and had written his answers secretly on a piece of paper which he placed under a quilt, the Sultan caused a hole to be made in the eastern wall and through this he left the summer house.
