Sunan an-Nasa'i, Volume 3, Book 21, Hadith 1936 (DarusSalam) ⓘ
It was narrated that Abu Aswad Ad-Dili said: "I came to Al-Madinah and sat with 'Umar bin Al-Khattab. A funeral passed by and the deceased was praised, and 'Umar said: 'It is granted.' Then another passed by and the deceased was praised, and 'Umar Said: 'It is granted.' Then a third passed by, and the deceased was criticized, and 'Umar said: 'It is granted.' I said: What is granted, O commander of the believers?' He said: 'I said what the Messenger of Allah said: Any Muslim for whom four people bear witness and say good things, Allah will admit him to Paradise.' We said: 'Or three?' He said: 'Or three.' We said: 'Or two?' He said: 'Or two."'
أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا هِشَامُ بْنُ عَبْدِ الْمَلِكِ، وَعَبْدُ اللَّهِ بْنُ يَزِيدَ، قَالاَ حَدَّثَنَا دَاوُدُ بْنُ أَبِي الْفُرَاتِ، قَالَ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ بُرَيْدَةَ، عَنْ أَبِي الأَسْوَدِ الدِّيلِيِّ، قَالَ أَتَيْتُ الْمَدِينَةَ فَجَلَسْتُ إِلَى عُمَرَ بْنِ الْخَطَّابِ فَمُرَّ بِجَنَازَةٍ فَأُثْنِيَ عَلَى صَاحِبِهَا خَيْرًا فَقَالَ عُمَرُ وَجَبَتْ . ثُمَّ مُرَّ بِأُخْرَى فَأُثْنِيَ عَلَى صَاحِبِهَا خَيْرًا فَقَالَ عُمَرُ وَجَبَتْ . ثُمَّ مُرَّ بِالثَّالِثِ فَأُثْنِيَ عَلَى صَاحِبِهَا شَرًّا فَقَالَ عُمَرُ وَجَبَتْ . فَقُلْتُ وَمَا وَجَبَتْ يَا أَمِيرَ الْمُؤْمِنِينَ قَالَ قُلْتُ كَمَا قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " أَيُّمَا مُسْلِمٍ شَهِدَ لَهُ أَرْبَعَةٌ قَالُوا خَيْرًا أَدْخَلَهُ اللَّهُ الْجَنَّةَ " . قُلْنَا أَوْ ثَلاَثَةٌ قَالَ " أَوْ ثَلاَثَةٌ " . قُلْنَا أَوِ اثْنَانِ قَالَ " أَوِ اثْنَانِ " .
