Mother's name.

שם האם

In Jewish tradition, when requesting a blessing or praying for someone's health, it is customary to mention the person's Hebrew name followed by their mother's Hebrew name. This is particularly common in prayers for healing, known as "Mi Sheberach," where the full phrase would be "[Name] ben/bat [Mother's Name]," indicating "[Name] son/daughter of [Mother’s Name]." This format enhances the spiritual connection and effectiveness of the prayers.
