Speaking about concluding the second Friday sermon with supplication.

The questioner : Many preachers make the second sermon entirely supplication, and this is undoubtedly a fundamental deviation from the Sunnah of the Messenger of Allah. Some of them mix it with some admonition and knowledge, as they did in the first sermon, but they conclude it with some supplication as well. We say that this conclusion is like concluding the prayer with a group supplication; this has no basis, and this has no basis. Perhaps you know what concluding the prayer with a group supplication is? That is, the imam, after he says the closing salam, turns to the congregation and may order them to glorify, magnify, and praise Allah, as if they had just embraced Islam today and did not know what to do after the obligatory prayer, so he teaches them these things whose permissibility is established by the Shari'ah. Then he raises his hands and supplicates, and he may raise his voice in supplication so that they say "Ameen" to him. All of this form has no basis in the Sunnah. Likewise, concluding the second Friday sermon—the second Friday sermon, yes, that is right—this conclusion is not prescribed.
Adherence. I am speaking now about adherence; because adhering to something that the Sunnah has not established is undoubtedly a religious innovation. However, sometimes what we said regarding qunut may apply to performing this supplication.
So I say: It is obligatory for every preacher to gradually make the second sermon exactly like the first; that is, he should not mix any supplication into it except in some cases and for a legitimate Shari'ah policy, except in some cases and for a legitimate Shari'ah policy, until people learn that the second sermon is the completion of the first sermon, about which our Lord (Mighty and Majestic) said: . The remembrance of Allah here is the sermon for the sake of admonition, reminding, and advice.
