Who among the following foreign travellers to India said the given words regarding the Delhi Sultanate? "When I entered Delhi, it was almost like a desert."

Muhammad- Bin- Tughlaq transferred his capital from Delhi to Devagiri. The plan proved disastrous due to Mongol Attack on North. And since this happened in summer, many people died because of inadequate water supply arrangements in Daulatabad; after only two years, the capital had to be shifted back again to Delhi, again at great loss, and it was said that Delhi was a ghost town for years after the move back. "When I entered Delhi, it was almost like a desert", wrote the famed North African travel writer, Ibn Battuta.
