What is obligatory for the listener of the Friday sermon

The Shaykh : That is because the one who sits to listen to the sermon has two obligations, and I hope you will pay attention now. The first obligation is listening, and the second obligation is paying attention. Paying attention is incompatible with sending blessings upon the Prophet (peace and blessings be upon him) in secret and glorifying Allah in secret. In that case, there is evidence for this, but I do not recall at this moment whether the reason for the revelation mentioned in the books of exegesis is established from the Prophet (peace and blessings be upon him). If some of our brothers among the students, like us, mention something in this regard, we will benefit from it.
Al-Halabi : What I remember is that it is in the prayer. As for the issue of the Friday sermon...

The Shaykh : The Friday sermon, yes, that is correct.
