Answer the call of arms when needed in defense of justice and truth .

This hadith encourages people to answer the call of arms and fight for a just cause. It is narrated from Ibn 'Abbas that the Prophet (ﷺ) said, “If you are called to arms then go forth”. This hadith teaches us that it is our duty as Muslims to stand up for justice and defend what is right, even if it means going into battle. We must remember that war should only be used as a last resort when all other peaceful options have been exhausted, and we must always strive for peace first before resorting to violence. We should also remember that war should never be used as an excuse for revenge or personal gain; rather, it should only be used in defense of justice and truth.
