A book by Adham Sharkawi that portrays glimpses from the life of Abu Bakr Al-Siddiq, may Allah be pleased with him, in Sharkawi's pure and eloquent literary style. The author highlights Abu Bakr's deeds, providing insight into this figure who is just below the prophets in rank and far above the people.

Sharkawi presents the doubts found in Abu Bakr's biography and mentions his noble ethics and virtues. As the title "Companion of Two" suggests, it recounts Abu Bakr's companionship with the Prophet Muhammad, peace be upon him, including the migration from Mecca to Medina and their stay in the cave.

The discussion continues to his caliphate, with his saying "Will the faith decrease while I am alive?"
