'Abdullah bin Yasar said: "I was sitting with sulaiman bin Sard and Khalid bin 'Urfutah, and they said that a man had died as a result of abdominal illness. They wanted to attend his funeral, and one of them said to the other: 'Didn't the Messenger of Allah (ﷺ) say: Whoever is killed by an abdominal illness, he will not be punished in his grave? The other said: 'Yes.'''

أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى، قَالَ حَدَّثَنَا خَالِدٌ، عَنْ شُعْبَةَ، قَالَ أَخْبَرَنِي جَامِعُ بْنُ شَدَّادٍ، قَالَ سَمِعْتُ عَبْدَ اللَّهِ بْنَ يَسَارٍ، قَالَ كُنْتُ جَالِسًا وَسُلَيْمَانُ بْنُ صُرَدٍ وَخَالِدُ بْنُ عُرْفُطَةَ فَذَكَرُوا أَنَّ رَجُلاً، تُوُفِّيَ مَاتَ بِبَطْنِهِ فَإِذَا هُمَا يَشْتَهِيَانِ أَنْ يَكُونَا شُهَدَاءَ جَنَازَتِهِ فَقَالَ أَحَدُهُمَا لِلآخَرِ أَلَمْ يَقُلْ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ يَقْتُلْهُ بَطْنُهُ فَلَنْ يُعَذَّبَ فِي قَبْرِهِ " . فَقَالَ الآخَرُ بَلَى .
