It was recorded by Imām Aḥmad (1/450): Yaḥyá ibn Zakarīyā narrated to us from his father, from Abū Isḥāq, from Abū al-Aḥwaṣ, from ʿAbdullāh, from the Prophet (ṣallá Allāhu ʿalayhi wa-sallam) with it. I said: This isnād [chain of transmission] consists of narrators, all of whom are trustworthy, the narrators of Muslim, so it is authentic except that Zakarīyā—who is the son of Abū Zāʾidah—heard from Abū Isḥāq—who is ʿAmr ibn ʿAbdullāh al-Sabīʿī—during his period of confusion. However, Sufyān also followed him from Abū Isḥāq with it, except he said: ".. cannot imitate me." It was recorded by Aḥmad (1/375, 400, 440), al-Tirmidhī (2277), Ibn Mājah (3946), and al-Dārimī (2/123-124), and al-Tirmidhī said: "A ḥasan ṣaḥīḥ ḥadīth."

It was also narrated by al-Ṭabarānī in "al-Awsaṭ" (1/67/2, no. 1244) from the route of al-Ḥajjāj ibn Arṭāh from Abū Isḥāq with it. And it has a corroborating narration from ʿAbdullāh ibn ʿAbbās, raised to the Prophet, with the wording: "Whoever sees me in a dream, then indeed he has seen me, for Satan cannot imitate me. In another wording: cannot resemble me." It was recorded by Aḥmad (1/279) from the route of Jābir, from ʿAmmār, from Saʿīd ibn Jubayr, from him. And its narrators are trustworthy, the narrators of Muslim, except for Jābir, who is al-Juʿfī, and he is weak. However, it came from another route from the narration of ʿAwf ibn Abī Jamīlah from Nadhīr al-Fārisī—who used to write the muṣḥafs—he said:
