What will be the fate of a nonpracticing Mushrik or a practicing Ahle-Kitab in the next life?

If a **nonpracticing** Mushrik or a **practicing** Ahle-Kitab or a **nonpracticing** Muslim lives an honest life, doesn't do any harm to anybody with his actions and with his words and engages his entire life helping the poor and distressed people, **according to Koran**, what will be his fate in the after life? Who is better? A dishonest and cruel man who is a Muslim by born? Or, an honest and benevolent man who is a Mushrik by born? Will he still go to hell? For example, what about Mother Teresa ?
