It was narrated that Abu Hurairah said:
“The Prophet (ﷺ) set out in the early morning and I did likewise. I prayed, then I sat. The Prophet (ﷺ) turned to me and said: ‘Do you have a stomach problem?’* I said: ‘Yes, O Messenger of Allah.’ He said: ‘Get up and pray, for in prayer there is healing.’” Another chain with similar wording. Abu `Abdullah said: A man narrated it to his people, then they were stirred up against him.
