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. (Using translation from Muslim 94a)
عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ بَشَّرَنِي جِبْرِيلُ أَنَّهُ مَنْ مَاتَ مِنْ أُمَّتِكَ لَا يُشْرِكُ بِاللهِ شَيْئًا دَخَلَ الْجَنَّةَ قَالَ قُلْتُ وَإِنْ زَنَى وَإِنْ سَرَقَ؟ قَالَ وَإِنْ زَنَى وَإِنْ سَرَقَ
