That being said, the likely meaning of describing these rivers as “from Paradise” is that their origin lies there, just as humanity’s own origin is in Paradise. Hence the ḥadīth does not conflict with the observable fact that these rivers flow from their well-known earthly sources. If this—or something similar—is not the intended sense, then the report belongs to the realm of the unseen, which we are required to accept in faith and submit to the one who conveyed it, in accordance with the Divine statement: “But no, by your Lord, they will not believe until they make you the judge in all that they dispute among themselves, then find within themselves no discomfort regarding what you have decided, and submit in full submission” (Qur’an 4:65).
113 – “Whoever says: There is no god but Allah alone, without partner; to Him belongs the dominion, and to Him belongs all praise, and He is powerful over all things — ten times after performing the dawn prayer, Allah will record for him ten good deeds, erase ten sins, raise him by ten ranks, and it will be equivalent for him to emancipating two slaves from among the descendants of Ismāʿīl. If he says it when evening comes, he will receive the same reward, and it will serve as a barrier against Satan until morning.”

Through Ibn ʿArafah’s route it was also transmitted by al-Khaṭīb in his History (12/389, 472).
I say: This chain is sound; its narrators are trustworthy — they are the narrators of Muslim except for this Qurān, and he himself is reliable.
It has a corroborating narration from Abū Ayyūb al-Anṣārī with the wording: “Whoever says, after he has prayed the dawn prayer …” and he quoted it in full.
