Spread knowledge & understanding about Islam ; Do good deeds ; Leave comfort zone & go out into the world ; Engage in acts outside physical travel such as writing or speaking about Islam online/offline etc..

The hadith narrated by Abu Umamah states that travelling for the sake of Allah is a form of jihad. This means that when one travels to spread knowledge and understanding about Islam, they are engaging in an act which is pleasing to God. This could include going on a pilgrimage or visiting other countries to teach people about Islam and its values. It also implies that even if one does not physically travel, they can still engage in jihad by spreading knowledge and understanding through other means such as writing or speaking about it online or offline. By doing this, one can help others learn more about their faith and become closer to God. Furthermore, this hadith teaches us that we should strive to do good deeds even if it requires us to leave our comfort zone and go out into the world.
