Which of the following is not correct about the Moroccan traveller Ibn Batuta?

He remained in that position for several years, until his return from India.

Travelling overland through Central Asia, Ibn Battuta reached Sind in 1333. He had heard about Muhammad bin Tughlaq, the Sultan of Delhi, and lured by his reputation as a generous patron of arts and letters, set off for Delhi, passing through Multan and Uch. The Sultan was impressed by his scholarship, and appointed him the qazi or judge of Delhi. He remained in that position for several years, until he fell out of favour and was thrown into prison. Once the misunderstanding between him and the Sultan was cleared, he was restored to imperial service, and was ordered in 1342 to proceed to China as the Sultan’s envoy to the Mongol ruler.
