From Aban Bin Taglub, From Abu Abdullah Ja’far -asws Bin Muhammad Al-Sadiq -asws having said: ‘When this Verse was Revealed: And there is none from the People of the Book except that he would believe in him [4:159] – the Verse.
He -asws said: ‘There would not remain anyone who rejects upon Isa -as Ibn Maryam -as what he -saww has come with regarding him -as , except that he would be a Kafir, nor anyone who rejects upon Ali -asws Bin Abu Talib -asws what the Prophet -saww said, except he would be a Kafir’’.
[17] On Return of the Imam Mehdi -asws : All Muslims believe that Imam Mehdi -asws will come to revive Islam, so the overcoming of the religion of Islam on all other religions has yet to take place as is predicted in the Holy Quran: هُوَ الَّذِي أَرْسَلَ رَسُولَهُ بِالْهُدَىٰ وَدِينِ الْحَقِّ لِيُظْهِرَهُ عَلَى الدِّينِ كُلِّهِ وَلَوْ كَرِهَ الْمُشْرِكُونَ {33} He is the One Who Sent His Rasool with the Guidance and the Religion of Truth in order to prevail it upon all the Religions, and even if the Polytheists dislike it [9:33] Therefore, a Divine Imam -asws has yet to revive the religion of Allah -azwj .
No other person or individual can claim to be a Divine authority. For someone to be able to claim divine authority they will have to have the attributes and qualities of a Prophet and Imam like the capability of being able to speak all languages and perform miracles. Each Prophet –as and Imam –as performed miracles when asked for a proof of being Appointed from Allah -azwj .
The false imams are only confined to servicing their followers using trickery and scholastic theology as they have never been able to make claims of Imamat for all inhabitants of the earth (i.e., jinn, human, birds, animals).
Statements of Al-Baqir -asws regarding the occurrence of Ghaibat المفيد في كتاب (الغيبة): بإسناده عن المفضل بن عمر، عن أبي عبد الله (عليه السلام) أنه قال: «إذا قام القائم (عليه السلام) تلا هذه الآية، مخاطبا للناس: فَفَرَرْتُ مِنْكُمْ لَمَّا خِفْتُكُمْ فَوَهَبَ لِي رَبِّي حُكْماً وَ جَعَلَنِي مِنَ الْمُرْسَلِينَ».
