As understood by a study of the three letters ن, ق and ص in the chapters Qalam, Qaf and Sad, the common points, in addition to the main principles of religion, consist in the Quran as the base of Divine Zikr, the prophets` invitation, patience and resistance, against hardships and purity in worshiping God. The letter ن in Qalam along with an oath to what is for record and registration, refers to the status of the greatest prophet of God and his moral and manner of life as being in full agreement with the Divine zikr. The letter ق in the chapter Qaf with an oath to the holy Quran, refers to resurrection as a necessary reality and views the Prophet`s mission as mentioning those people of ready heart to avoid opposing God. The letter  ص in the chapter Sad with an oath to the holy Quran as being full of sermon has put monotheist as the base for the prophets` mission and invited people to the Divine obedience.
