It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that he said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever fasts Wednesday, Thursday and Friday, Allah Almighty will build for him a palace in Paradise whose outside can be clearly seen from its inside and its inside from its outside."
Imam Abu Ya'la also narrated, through his own chain, a narration of similar meaning from Sayyiduna Ibn Abbas (may Allah be pleased with them both), and the narrations of Sayyiduna Ibn Abbas and Sayyiduna Ibn Umar (may Allah be pleased with them) will come shortly in their relevant chapters.
Baqiyyah also narrated this same hadith with his chain from Sayyiduna Ibn Umar (may Allah be pleased with them both).
