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." (Using translation from Bukhārī 7487)
عَنِ النَّبِيِّ ﷺ قَالَ «أَتَانِي جِبْرِيلُ فَبَشَّرَنِي أَنَّهُ مَنْ مَاتَ مِنْ أُمَّتِكَ لَا يُشْرِكُ بِاللهِ شَيْئًا دَخَلَ الْجَنَّةَ» قُلْتُ وَإِنْ سَرَقَ وَإِنْ زَنَى؟ قَالَ «وَإِنْ سَرَقَ وَإِنْ زَنَى»
