But the Messenger and those who believed with him fought with their wealth and their lives. Those will have [all that is] good and it is those who are the successful.

Tafsir
The Messenger and the believers with him did not remain behind from striving in Allah’s path, as these people did. Instead, they strived in Allah’s path with their wealth and their lives. Their reward from Allah is that they will receive worldly benefits, such as victory and gains of war, as well as benefits in the Afterlife, which includes entry into Paradise and successful attainment of their desires and salvation from what they fear.
