Has an authentic hadith been reported concerning the saying of "Allahumma ajirni min an-nar" (O Allah, protect me from the Fire) seven times after the Fajr and 'Isha prayers?

The aforementioned Hadith, which contains the supplication "O Allah, protect me from the Fire" seven times after the Fajr and Maghrib prayers, is weak, and it does not mention the 'Isha prayer. The correct (narration) is that whoever asks Allah for Paradise three times, Paradise says: "O Allah, admit him to Paradise," and whoever seeks refuge from the Fire three times, the Fire says: "O Allah, protect him from the Fire." This is not restricted to specific prayers or times, and it is recommended to say it frequently.
