Step 1: Understand the Question: The objective is to identify the false statement regarding the life and journeys of the 14th-century Moroccan traveler, Ibn Battuta.
Step 2: Analyze Each Statement:
Statement (1): This statement is accurate. Ibn Battuta's travelogue is known as the \textit{Rihla}, meaning "The Journey," and was written in his native Arabic.
Statement (2): This statement is accurate. He originated from Tangier, Morocco, and belonged to a family of Islamic legal scholars (ulama). He was also proficient in \textit{shari'a}.
Statement (3): This statement is accurate. Ibn Battuta's writings include detailed accounts of Indian trade and commodities, specifically mentioning the high quality and cost of fine textiles such as muslin from Bengal.
Statement (4): This statement is inaccurate. In 1342, following a period of disfavor, Sultan Muhammad bin Tughlaq dispatched Ibn Battuta as an envoy not to Persia, but to the Mongol court in China. This mission to China constitutes a significant portion of the later sections of his \textit{Rihla}.
Step 3: Conclusion:
The inaccurate statement asserts that Ibn Battuta was sent as an envoy to Persia. His actual assignment was to China.
