12er Shia Imam Travels Back In Time to Help Prophet Sulaiman

الَ الَّذِي عِنْدَهُ عِلْمٌ مِنَ الْكِتَابِ أَنَا آتِيكَ بِهِ قَبْلَ أَنْ يَرْتَدَّ إِلَيْكَ طَرْفُكَ ۚ فَلَمَّا رَآهُ مُسْتَقِرًّا عِنْدَهُ قَالَ هَٰذَا مِنْ فَضْلِ رَبِّي لِيَبْلُوَنِي أَأَشْكُرُ أَمْ أَكْفُرُ ۖ وَمَنْ شَكَرَ فَإِنَّمَا يَشْكُرُ لِنَفْسِهِ ۖ وَمَنْ كَفَرَ فَإِنَّ رَبِّي غَنِيٌّ كَرِيمٌ {40} [Pickthal 27:40] One with whom was knowledge of the Scripture said: I will bring it thee before thy gaze returneth unto thee. And when he saw it set in his presence, (Solomon) said: This is of the bounty of my Lord, that He may try me whether I give thanks or am ungrateful. Whosoever giveth thanks he only giveth thanks for (the good of) his own soul; and whosoever is ungrateful (is ungrateful only to his own soul's hurt). For lo! my Lord is Absolute in independence,Bountiful.

[Pooya/Ali Commentary] A large, powerful jinn offered his services and assured Sulayman that he would do it before he would rise from his council. However strong and big a creature might be, it was not possible for him to go to a distant land and bring her and her throne in a few moments, unless the jinn had supernatural powers to do it. Although the jinn had boasted of his strength and supernatural power, yet when a man who had knowledge of the book said that he would bring them to him within the twinkling of an eye, Sulayman gave him permission. Soon the Queen, with her throne, was before him. See commentary of Rad: 43 to know about him who had the knowledge of the book. It is reported by Abu Ishaq Thalabi that Abdullah bin Salam asked the Holy Prophet to give the name of the man who had knowledge of the book and brought the queen of Sheba with her throne within the twinkling of an eye. The Holy Prophet said: "It was Ali." It is stated in Minhaj al Sadiqin and Umdat al Bayan that then the Holy Prophet said to Ali: "O Ali, you helped all the prophets of Allah incognito (concealed from view), and you help me in propria persona (in person) manifestly." Ali ibn abi Talib is known as mazhar al aja-ib and mazhar al ghara-ib because, as willed by Allah, he used to appear in different forms to carry out divine plans under very special circumstances. These two epithets are exclusively reserved for Ali. Even today the true believers invoke Allah to send him for help. The famous dua, known as Nadi Ali, which the Holy Prophet recited, as commanded by Allah, at Khaybar refers to Ali as mazhar al aja-ib. Ali ibn abi Talib is also known as mushkil kusha, the remover of hardships. In every age, to many persons he comes personally to remove hardships. Through his name great spiritual achievements are attained. The Holy Prophet, and after him, Ali are acknowledged as the most superior possessors of the spiritual powers.

The 12er Shia school of theology divides Muslims in two groups.
They are:
  a) Exoteric (Ammi)
 b) Esoteric (Khassa)

 Exoteric (Ammi)
 The exoteric are the Ammi who the 12ers refer to as the Sunnis. Since we are Sunni we are referred to common people, and due to this only common knowledge will be shared in public.

Esoteric (Khassa)
 The esoteric are the khassa who are special people within the 12er Shia. Within this group another type of knowledge is shared which is intended for only a small group of people.

 So supposedly even the knowledge of Imam Ali (as) helping the previous Prophets was hidden from the Prophets themselves, yet the esoteric group of people knew that all along that it was Ali who was travelling back in time to help the previous Prophets.
 This is why the 12ers have ahadith like this in their books:

 Mohammed bin al-Hasan bin Ahmed bin al-Waleed related to me from Mohammed bin al-Hasan as-Saffar… from Mohammed bin Qays and Aamir bin as-Simt that Abu Ja'far (as) related that the Prophet (pbuh) said: On the Day of Resurrection, some people dressing clothes of light with luminous faces whom will be identified by the signs of prostration will come. They will overstep the rows until they stand in front of the Lord of the worlds. The prophets, angels, shahids, and righteous people will envy them. Omar bin al-Khattab asked: O Allah's Messenger (pbuh), who are they whom the prophets, angels, shahids, and righteous men will envy? The Prophet answered: They will be our Shia, and Ali (as) will be their imam. ( Mishkat ul-Anwar; 97, al-Burhan; 4:293 H.13, Bihar ul-Anwar; 7:179 H.18.)
