Final answer:
The Muslim army halted in Ma'an, Jordan, due to a disagreement over leadership and uncertainty about the enemy's location.
Step-by-step explanation:
The Muslim army stopped in Ma'an, a city in present-day Jordan, due to its strategic location on the trade routes connecting the Arabian Peninsula with Syria and Palestine. Ma'an served as a crucial stopping point for caravans traveling between these regions, providing resources, supplies, and rest for the Muslim army.
The subsequent Battle of Mu'tah took place near Ma'an, where the Muslims faced significant challenges, including the death of prominent leaders. While Ma'an itself did not witness a major battle, the events surrounding it reflect internal tensions and strategic complexities within the Muslim army during this historical period.
