question #3 Sahih al-Bukhari 7487, Book 97, Hadith 113 : What role does the belief in Allah’s oneness play in the salvation of a believer?

The Prophet (ﷺ) said, Gabriel came to me and gave me the glad tidings that anyone who died without
worshipping anything besides Allah, would enter Paradise. I asked (Gabriel), ‘Even if he committed
theft, and even if he committed illegal sexual intercourse?’ He said, ‘(Yes), even if he committed theft,
and even if he Committed illegal sexual intercourse.”
