Al-awasim refers to a term used in Islamic law which means "compulsory military service". This is a rule that says that every able-bodied Muslim man is required to join the military if there is a just war being fought, and it is mandatory for the community's survival.
To put it in simpler terms, imagine if you were playing with your friends and someone was trying to hurt you all. Instead of running away or hiding, you and your friends would work together to fight back and protect yourselves. This is a similar idea to al-awasim - when there is a threat to your community or your religious beliefs, it is important for everyone to come together and help defend against it.
In Islam, al-awasim is seen as a way to protect the community and promote justice. It is a responsibility that all able-bodied Muslim men must take seriously, as it is considered an important duty to protect their families, neighbors, and fellow Muslims.
