Arabic hadith text
وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالَ ابْنُ الْمُثَنَّى حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ وَاصِلٍ الأَحْدَبِ، عَنِ الْمَعْرُورِ بْنِ سُوَيْدٍ، قَالَ سَمِعْتُ أَبَا ذَرٍّ، يُحَدِّثُ عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ قَالَ "أَتَانِي جِبْرِيلُ - عَلَيْهِ السَّلاَمُ - فَبَشَّرَنِي أَنَّهُ مَنْ مَاتَ مِنْ أُمَّتِكَ لاَ يُشْرِكُ بِاللَّهِ شَيْئًا دَخَلَ الْجَنَّةَ " . قُلْتُ وَإِنْ زَنَى وَإِنْ سَرَقَ . قَالَ "
Translation
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.
