I saw the Prophet ﷺ delivering a sermon while mounted on a she-camel, with an Abyssinian man holding its reins.
أخبرنا يعقوب بن إبراهيم قال حدثنا ابن أبي زائدة قال أخبرني إسمعيل بن أبي خالد عن أخيه
رأيت النبي ﷺ يخطب على ناقة وحبشي آخذ بخطام الناقة
[Its chain is hasan] Ibn Majah narrated it in "Establishing Prayers," chapter "What Has Been Said Regarding the Sermon at the Two Eids," hadith 1284, from the hadith of Ismail with this wording, and it is also found in Kubra, hadith 1782.
