Abdullah bin Yasar says: I was sitting with Sayyiduna Sulaiman bin Surad and Sayyiduna Khalid bin 'Urfatah (may Allah be pleased with them). People informed that a certain man had died due to a stomach illness. They wanted to perform his funeral prayer, and one said to the other: Did the Noble Prophet (peace and blessings be upon him) not say that whoever dies due to a stomach illness will never be punished in the grave? The other replied: Yes, he did say that.
