It is narrated from Sayyiduna Itban bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) performed the Duha prayer in his house, so the noble Companions also stood behind him, and all of them performed the Duha prayer in his house. Imam Abu Bakr (may Allah have mercy on him) says that the house referred to is the house of Sayyiduna Itban bin Malik (may Allah be pleased with him).
