Is it permissible to use the aforementioned topic, especially the phrase, "I sought mercy among the Jews… I sought faith from Abu Lahab," as a sermon?

The discourse mentioned contains a little truth and much falsehood, and it exhibits the characteristic of despair and despondency, which is inconsistent with the spirit of a believer. The assertion that Muslims are devoid of all good and that it must be sought from others is clear error, for the Prophet, peace and blessings be upon him, said: "Whoever says 'the people are ruined' is the most ruinous of them." This Ummah contains great good, and there continues to be a group upholding the command of Allah the Almighty, with whom one can cooperate for good. What came in the question is not suitable to be an admonition, for its harm is greater than its benefit.
