Emphasizing the call to tawhid (the oneness of Allah) in Friday sermons

Question:
Honorable Shaykh, may Allah grant you success, there is no doubt that the Friday sermon is one of the most important means of da'wah (calling others to Islam). When we advise some of the preachers to increase their call to tawhid, or to warn against shirk (associating partners with Allah), or to call to prayer, and to enjoin what is right and forbid what is wrong, these are matters that are deeply rooted in the mind. The call to them may involve giving examples to the people, or perhaps dictating to them, because they already know these things. So I ask for your guidance.

Answer:
This is a mistake; not everyone knows these things. Many people are ignorant of these matters. Also, even those who know them may forget or become heedless of them, so they are reminded of them. He calls to tawhid in the sermon, and he also calls to... he enjoins what is right and forbids what is wrong. He addresses various topics in the sermon, mentioning them under a single theme, covering what people need in their worship, their creed, and their transactions.
He does not stick to a single topic and repeat it every Friday and in every sermon. Rather, he varies it according to the state of the people. However, he always focuses on tawhid at the beginning of the sermon, making tawhid the entry point. Yes. Then he proceeds to what people need in their transactions, their worship, and the matters in which they fall into error, the violations that come from them.
