According to the holy Quran during the history of the human being, the earth has never been without God’s Proof and Allah (SWT) has sent a guide to all nations. In Ayah 7 of Surah Ra’ad, Allah (SWT) said: “Indeed you are a warner and there is one guide for every society (nation, people).” Therefore, there is always a warner and guide present in human societies who is chosen and appointed by God. For the commentary of the above Ayah, Imam Sadeq (AS) said: At any time, there is an Imam from our dynasty who guides people to what the Prophet of God (PBUH) has brought (the religion of Islam) [1]. From the above Ayah and the narration by Imam Sadeq (AS) it can be realized that any time God’s Proof is needed on this earth.
