Does dying in Ramadan mean entering Paradise without reckoning, based on the Prophet's saying: "When Ramadan comes, the gates of Paradise are opened, the gates of Hell are closed, and the devils are chained"?

The gates of Paradise are opened in Ramadan (definition) to encourage those who strive, and the gates of Hell are closed because the people of faith abstain from sins. This does not mean that whoever dies in Ramadan enters Paradise without reckoning. Rather, those who enter Paradise without reckoning are "those who do not seek ruqyah (definition), nor practice cauterization, nor believe in omens, and upon their Lord they rely," in addition to performing righteous deeds.
