question #3 Sahih al-Bukhari 6323, Book 80, Hadith 20 : How does the recitation of a particular supplication relate to one’s fate in the afterlife according to Islamic teachings?

The Prophet (ﷺ) said, “The most superior way of asking for forgiveness from Allah is: ‘Allahumma anta
Rabbi la ilaha illa anta. Khalaqtani wa ana `Abduka, wa ana ‘ala ‘ahdika wa Wa’dika mastata’tu abu’u
Laka bi ni ‘matika wa abu’u Laka bidhanbi; faghfirli fa’innahu la yaghfiru-dh-dhunuba ill a ant a.
A’uidhu bika min sharri ma sana’tu.’ If somebody recites this invocation during the night, and if he
should die then, he will go to Paradise (or he will be from the people of Paradise). And if he recites it
in the morning, and if he should die on the same day, he will have the same fate.”
