Respond immediately when called upon by Muslim ruler; Strive to do what is right; Stand up for justice; Have pure intentions while engaging in any kind of struggle/fight; Sacrifice one's own comfort or safety if needed .

This hadith speaks about the importance of jihad and intentions in Islam. After the conquest of Mecca, Muslims were encouraged to take part in jihad or struggle for a good cause instead of migrating away from their homeland. It also encourages Muslims to respond immediately when they are called upon by their Muslim ruler to fight for a good cause. This hadith teaches us that we should always strive to do what is right and just even if it means sacrificing our own comfort or safety. We should also be willing to stand up for justice whenever we are called upon by our leaders or rulers. Lastly, this hadith reminds us that our intentions must always be pure when engaging in any kind of struggle or fight as it will determine whether we will receive reward from Allah or not on the Day of Judgment.
