Narrated Anas bin Malik:The Prophet (ﷺ) noticed the absence of Thabit bin Qais. A man said, "O Allah's Messenger (ﷺ)! I shall bring you his news." So he went to him and saw him sitting in his house drooping his head (sadly). He asked Thabit, "What's the matter?" Thabit replied, "An evil situation: A man used to raise his voice over the voice of the Prophet (ﷺ) and so all his good deeds have been annulled and he is from the people of Hell." The man went back and told the Prophet (ﷺ) that Thabit had said so-and-so. (The sub-narrator, Musa bin Anas said, "The man went to Thabit again with glad tidings)." The Prophet (ﷺ) said to him, "Go and say to Thabit: 'You are not from the people of Fire, but from the people of Paradise."
حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا أَزْهَرُ بْنُ سَعْدٍ، حَدَّثَنَا ابْنُ عَوْنٍ، قَالَ أَنْبَأَنِي مُوسَى بْنُ أَنَسٍ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ أَنَّ النَّبِيَّ صلى الله عليه وسلم افْتَقَدَ ثَابِتَ بْنَ قَيْسٍ، فَقَالَ رَجُلٌ يَا رَسُولَ اللَّهِ، أَنَا أَعْلَمُ لَكَ عِلْمَهُ. فَأَتَاهُ فَوَجَدَهُ جَالِسًا فِي بَيْتِهِ مُنَكِّسًا رَأْسَهُ، فَقَالَ مَا شَأْنُكَ فَقَالَ شَرٌّ، كَانَ يَرْفَعُ صَوْتَهُ فَوْقَ صَوْتِ النَّبِيِّ صلى الله عليه وسلم فَقَدْ حَبِطَ عَمَلُهُ، وَهْوَ مِنْ أَهْلِ النَّارِ. فَأَتَى الرَّجُلُ فَأَخْبَرَهُ أَنَّهُ قَالَ كَذَا وَكَذَا. فَقَالَ مُوسَى بْنُ أَنَسٍ فَرَجَعَ الْمَرَّةَ الآخِرَةَ بِبِشَارَةٍ عَظِيمَةٍ، فَقَالَ " اذْهَبْ إِلَيْهِ فَقُلْ لَهُ إِنَّكَ لَسْتَ مِنْ أَهْلِ النَّارِ، وَلَكِنْ مِنْ أَهْلِ الْجَنَّةِ ".
