It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever fasts on Wednesday, Thursday and Friday, Allah Almighty will build for him a house in Paradise whose outside can be seen from its inside and whose inside can be seen from its outside."
No one narrated this hadith from Maymun bin Mihran except Salih bin Jabalah, and Shihab bin Khirash is alone in narrating it from him.
