Bismillah,

Mr Tijani continued to mislead his readers by saying at page 83 of his book Shia Hum Ahle Sunna:

Translation:

What strengthens our conviction that the Twelve Imams from Ahl al-Bayt were never tutored by any of the Ummah’s scholars is the fact that no historian, nor traditionalist  nor biographer, has ever narrated saying that one of the Imams from Ahl al-Bayt learned what he knew from some sahaba or tabi`een as is the case with all the Ummah’s scholars and Imams.

I will quote just two examples, where clearly stated that Aimma from Ahlalbayt took companions and others as a teachers (shaykhs).

Ibn Hajar al-Asqalani in “Tahzib at-Tahzib” 1/310, Muasasat Risalah, Bio of Imam Jafar ibn Muhammad ibn Al-Husayn.

Translation:

and he narrated from his father, Muhammad ibn al-Munkadir, Ubeydullah ibn Abi Rafe, Ata, Urwa, and father of his mother al-Qasim ibn Muhammad, Nafi, az-Zuhri and Muslim ibn Abu Maryam.

Ibn Hajar al-Asqalani in “Tahzib at-Tahzib” 1/310, Muasasat Risalah, Bio of Imam Ali ibn al-Husayn.
