This article is an introduction (pishguftar) that Martyr Murtadha Mutahhari wrote for his book Khadamat-e mutaqabil-e Islam wa Iran (The Mutual Services of Islam and Iran) first published in 1349 H.Sh./1960. The translation of this book is under way and will soon be published by the Sazman-e Tablighat-e Islami, and we hope to publish some parts of it in the future in al-Tawhid.
