Someone said, "I saw in a dream that I was prostrating on the forehead of the Prophet ﷺ. I told the Messenger of Allah ﷺ about this, and he said, 'Indeed, one soul meets another.'" Then the Prophet ﷺ inclined his head like this, placing his forehead against the forehead of the Prophet ﷺ.
رأيت في المنام أني أسجد على جبهة النبي ﷺ، فأخبرت بذلك رسول الله ﷺ فقال: إن الروح لتلقى الروح، وأقنع النبي ﷺ رأسه، هكذا، فوضع جبهته على جبهة النبي ﷺ.
Ahmad (21864), Ibn Abu Shayba (11/78), and Tabarani in Al-Kabir (4/97) all narrated it through the route of Hammad bin Salama, who said, Abu Jafar Khatami informed us, from Umara bin Khuzayma bin Thabit, that his father said, then he mentioned it. Its isnad is sahih. The hadith has other routes as well, and this is the most sahih of them.
