It is narrated from Sayyiduna Abu Musa (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever prays four rak'ahs of Duha (the forenoon prayer) and four rak'ahs before the first prayer (i.e. Zuhr), a house will be built for him in Paradise in return for them."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Abu Burdah (may Allah have mercy on him) except Abdullah bin Ayyash (may Allah have mercy on him), and from Abdullah bin Ayyash (may Allah have mercy on him) only Ibrahim bin Muhammad al-Hamdani (may Allah have mercy on him), while Sahl bin Uthman (may Allah have mercy on him) is alone in it."
