How can the Hadith "There is no ṭīrah (evil omen)" be reconciled with Hadiths such as "The world is a prison for the believer and a paradise for the disbeliever," and "Be in this world as if you are a stranger or a transient passerby"?

Texts have been وردت in the Quran and Sunnah that belittle the importance of this world and diminish it in the believer's soul, such as the hadith "This world is the prison of the believer and the paradise of the disbeliever," and "Be in this world as if you are a stranger or a wayfarer." These texts call for asceticism regarding this world and for utilizing time in righteous deeds, because the worldly pleasures are few compared to the pleasures of the hereafter. The revelation's dissuasion from inclining towards this world is not among the forbidden pessimism, because pessimism is the [evil] omen that means the heart's fear of matters that have no effect, and it contradicts monotheism because it severs reliance on Allah and depends on illusion.
