To what extent are the circulated sayings and hadiths authentic, including the story of "one of the Salaf" and the virtues of certain Quranic surahs, and the subsequent warnings and urging to disseminate them?

The phrase "There is no god but Allah, Lord of the seven heavens and Lord of the Magnificent Throne" is part of the supplication for distress. As for the supplication "O Allah, whatever blessing has come to me in the morning...", its hadith (definition) is weak. The story of the man afflicted with leprosy and the hadith "Ten things prevent ten things" have not been mentioned, and one must beware of lying about the Prophet, may Allah bless him and grant him peace. Regarding Surah (definition) Al-Waqi'ah, a weak hadith has been reported about it preventing poverty, while Surah Al-Mulk has been proven by authentic hadiths to prevent the torment of the grave. One should refrain from spreading these statements for which there is no evidence.
