From Sahih Muslim (Hadith 272):
I heard Abu Dharr narrating it from the Apostle (ﷺ) that he observed:Gabriel came to me and gave me the tidings: Verily he who died amongst your Ummah without associating anything with Allah would enter Paradise. I (the narrator) said: Even if he committed adultery and theft. He (the Holy Prophet) said: (Yes), even if he committed adultery and theft
