Prayer: Is it obligatory to mention Lady Fāṭimah (a) in the second Friday sermon?

English:

Question #624:

Is it obligatory to mention the name of Fātimah al-Zahrā’s (a.) as an Imam of Muslims in the second sermon, or is it obligatory to mention her name with the intent of being mustaḥabb?

Answer #624:

The concept of Imams of Muslims does not apply to Fātimah al-Zahrā (a.), and it is not obligatory to mention her blessed name in the Friday sermon, but there is no problem in seeking blessings through mentioning her noble name (a). It is, in fact, a required thing and makes one gain rewards.
