Statement 1 is correct. The famous Sun Temple of Multan was indeed visited and described by several foreign travelers and chroniclers, including Hiuen Tsang (Xuanzang) in the 7th century, and later Arab geographers and historians like Abu Zayd al-Sirafi (likely Abuzaiyid), Al Masudi, and Alberuni in the 9th, 10th, and 11th centuries respectively. Statement 2 is also correct. Sambapur is a historical name for Multan, derived from the legend of Sambha (son of Krishna) establishing the Sun Temple there after being cured by sun worship. Pilgrimage to this temple (Sambapur) was a major centre for Sun worship in the region.
