I asked Ibn Umar, "Do you pray the Duha prayer?"He said, "No."I asked, "Did Umar pray it?"He said, "No."I asked, "Did Abu Bakr pray it?"He said, "No."I asked, "Did the Prophet ﷺ pray it?"He said, "I do not think so."
حدثنا وكيع حدثنا شعبة عن توبة العنبري
قلت لابن عمر أتصلي الضحى قال لا قلت فصلاها عمر قال لا قلت صلاها أبو بكر قال لا قلت أصلاها النبي ﷺ قال لا إخاله
Its isnad is sahih. Tawbah Anbari, his reliability was already established at 54, and I can add that Bukhari mentioned him in Kabir 1/1/155-156. I did not find the hadith in Majma al-Zawaid. It appears likely to be found in one of the six books, indeed it is in Sahih Bukhari 3/42, transmitted through Yahya from Shubah.
