صَحِيحُ مُسْلِمٍ
Sahih Muslim 28 b
The Book of Faith
The evidence that one who dies believing in tawhid will definitely enter paradise
وَحَدَّثَنِي أَحْمَدُ بْنُ إِبْرَاهِيمَ الدَّوْرَقِيُّ، حَدَّثَنَا مُبَشِّرُ بْنُ إِسْمَاعِيلَ، عَنِ الأَوْزَاعِيِّ، عَنْ عُمَيْرِ بْنِ هَانِئٍ، فِي هَذَا الإِسْنَادِ بِمِثْلِهِ غَيْرَ أَنَّهُ قَالَ " أَدْخَلَهُ اللَّهُ الْجَنَّةَ عَلَى مَا كَانَ مِنْ عَمَلٍ " . وَلَمْ يَذْكُرْ " مِنْ أَىِّ أَبْوَابِ الْجَنَّةِ الثَّمَانِيَةِ شَاءَ " .
It is narrated on the authority of Umar b. Hani with the same chain of transmitters with the exception of these words: Allah would make him (he who affirms these truths) enter Paradise through one of the eight doors which he would like.
