Question

what caused the muslim army to grow over the course of the war? the muslims captured people from other tribes and then forced them to fight in the army. there were traitors in the meccan army who came over to the muslim side. people began to believe that god was helping the muslim army so they joined them in the fight.

Explanation:

In historical - religious contexts, the belief in divine support often motivated people to join a cause. For early Muslim armies, the perception of God's assistance was a powerful factor in attracting new members. Forcibly conscripting captured people is not a widely - accepted or predominant reason for the growth of the Muslim army. Traitors defecting from the Meccan army is also not the main cause of the growth.

Answer:

People began to believe that God was helping the Muslim army so they joined them in the fight.
