Step-by-step explanation:
The hajj of Mansa Musa I communicated several significant messages. Firstly, it showcased his devotion to Islam, evident in the undertaking of the pilgrimage itself, which is one of the five pillars of Islam. His journey also highlighted his enormous power, as the king of the expansive Mali Empire, and his profound wealth, displayed through the extravagant entourage, generous gifts of gold, and the impact his spending had on the economies of regions he visited. Therefore, the correct answer to the student's question is 4) All of the above: Mansa Musa's hajj demonstrated his devotion to Islam, his enormous power, and his wealth.
Mansa Musa's pilgrimage to Mecca in 1324 significantly affected the regions he passed through, including the Mediterranean and Cairo, where his liberal dispersal of gold caused a devaluation of the metal, creating an economic impact that lasted for several years. This exhibition of generosity not only affirmed his adherence to the charitable aspects of Islam but also solidly established his status as one of the wealthiest individuals of that time. Furthermore, his investments in educational centers like Timbuktu after his return solidified Mali's importance as both a commercial and intellectual hub in the Islamic world.
