I asked the Messenger of Allah ﷺ about His statement, "For them are good tidings in the worldly life" [Yunus 10:64]. He said, "It refers to the righteous dream that a believer sees or that is seen for him."Harb said in his narration, "Yahya bin Abu Kathir told me."
حدثنا محمد بن بشار حدثنا أبو داود حدثنا حرب بن شداد وعمران القطان عن يحيى بن أبي كثير عن أبي سلمة قال نبئت
سألت رسول الله ﷺ عن قوله {لهم البشرى في الحياة الدنيا} قال هي الرؤيا الصالحة يراها المؤمن أو ترى له قال حرب في حديثه حدثني يحيى بن أبي كثير
[Hasan]Ibn Majah also narrated it in the Book of the Interpretation of Dreams, Chapter on the Righteous Dream Seen by a Muslim or Shown to Him, no. 3898, from the hadith of Yahya bin Abu Kathir with the same wording. Hakim graded it sahih according to the criteria of the two Shaykhs, 4/391, and Dhahabi agreed with him (! !), though its chain is daif. It is also found in Musnad Abu Dawud Tayalisi, no. 583. The hadith has corroborating narrations, among them the previously mentioned hadith, no. 2273.
