The important impact that Mansa Musa's Hajj had on Mali was that it brought significant attention and recognition to the empire. This pilgrimage showcased Mali's wealth and power to the rest of the Islamic world, leading to increased trade and diplomatic relations. Mansa Musa’s Hajj also played a crucial role in spreading Islam further throughout the region, solidifying its influence as the dominant religion in Mali. Additionally, the Hajj allowed Mansa Musa to establish connections with influential Islamic scholars and leaders, enabling him to bring back scholars and architects to Mali who would help in the further development of the empire. The statement about other religions besides Islam, Misa being kicked out is incorrect and does not relate to the impact of Mansa Musa's Hajj.
