When little Şaban turned seven, his only dream was to pray at the Şeyh Şaban-ı Veli Mosque in Kastamonu. Şaban's mother, Emine, had promised her husband on his deathbed that she would take their son to pray at Pir Hazretleri's mosque for the first time. However, they have no money for the journey. Moreover, after their father's death, they are struggling with seizures and creditors. Their neighbors give them a cow on trust to help them make ends meet. They plan to save up for the journey by selling the cow's milk and go to Kastamonu for the first prayer. Collecting the funds does not seem easy. Someone suggests to Emine that if she dilutes the milk with water before selling it, they will achieve their goal more easily. Emine’s heart begins to ache. Faced with the danger of not being able to fulfill her son’s noble intention, she reluctantly begins to dilute the milk. In this way, they manage to save the necessary amount in a short time.
