on the internet, you may have seen many cheats, but none matches the excellence of efendi
here is what he posted on his blog

under the heading

al-Mufid taught masoom imam!

Ibn Abil Hadeed al-Mo’tazaly
in his commentary on Nahjul
Balaghah writes that once Sheikh Mufid saw Fatima al-Zahra, peace
be upon her, in his dream. She was accompanied by her two young
sons, al-Hasan and al-Husain, peace be upon them. Addressing him,
she said: “O my Sheikh, teach Fiqh (Jurisprudence) to these two
boys of mine.” Next day, Fatimah, the mother of Seyyid Murtadha
and Syed al-Radhi came to Sheikh, holding hands of her two young
sons, and uttered the same words which Fatemah al-Zahra, peace be
upon her, had uttered in his dream.

now, let us forget about the fact that what he quoted is by ibn abil hadeed
even if you read what is written, no where it says
“he taught them”
