A righteous man died, and his funeral was carried out. When we returned, Khalid bin Arfata and Sulayman bin Surad met us, both of whom had been companions of the Prophet. They said, "You went ahead of us with this righteous man."The people mentioned that he had suffered from a stomach ailment and that they had feared the heat would affect his body.Then one of them looked at his companion and said, "Did you not hear the Messenger of Allah ﷺ say, 'Whoever is killed by his stomach will not be punished in his grave'?"
حدثنا قران حدثنا سعيد الشيباني أبو سنان
مات رجل صالح فأخرج بجنازته فلما رجعنا تلقانا خالد بن عرفطة وسليمان بن صرد وكلاهما قد كانت له صحبة فقالا سبقتمونا بهذا الرجل الصالح فذكروا أنه كان به بطن وأنهم خشوا عليه الحر قال فنظر أحدهما إلى صاحبه فقال أما سمعت رسول الله ﷺ يقول من قتله بطنه لم يعذب في قبره
