Narrated Zaid bin Khalid Al-Juhani: That the Messenger of Allah ﷺ said, "Whoever prepares a fighter in Allah's cause, he has participated in a military expedition, and whoever watches after the family of a fighter, he has participated in a military expedition". Abu 'Eisa said: This Hadith is Hasan Sahih.
This hadith encourages us to be generous with our time and resources when it comes to helping those who are fighting for the cause of Allah. It reminds us that even if we cannot physically join them on their mission, there are still ways we can contribute by providing support from afar or taking care of their families while they are away. By doing so, we will be rewarded as if we were actually on the battlefield ourselves!
