question #1 Sahih al-Bukhari 2815, Book 56, Hadith 31 : What is the significance of martyrdom in Islam, especially for those who have committed sins?

“Some people drank alcohol in the morning of the day (of the battle) of Uhud and were martyred (on
the same day).” Sufyan was asked, “(Were they martyred) in the last part of the day?)” He replied,
“Such information does not occur in the narration.”
