When the time came to defend the country against a powerful enemy, young Muhammad stood shoulder to shoulder with the young men of his land to defend his people in their terrible strife. His sincerity in friendship and his honesty in his dealings endeared him to all those far and near, who called him by the name Amin, which means trustworthy. His marriage with Khatidja showed him to be a man of devotion, a man of affection, and an honorable man as husband, father, and citizen of the town he lived in.
