Final answer:

Explanation:
The student is asking how to calculate the difference between years in the Islamic calendar, known as the Hijri calendar. Specifically, they are looking to find out what the year 1438 AH minus the year 139 AH equals in the context of Islamic history.
To calculate this, we subtract the smaller number (139) from the larger one (1438). The result, 1299 AH, represents the number of years that have passed between the two given years in the Islamic calendar.
The Islamic calendar begins with the Hijra, the emigration of the Prophet Muhammad from Mecca to Medina in 622 CE, which marks the year 1 AH (Anno Hegirae or 'in the year of the Hijra'). Therefore, 1438-139 AH in Islam refers to a span of 1299 lunisolar years in Islamic history.
