Muaz arrived from Yemen and said, "Messenger of Allah, I saw some men..." and he mentioned the rest of its meaning.
حدثنا ابن نمير حدثنا الأعمش قال سمعت أبا ظبيان يحدث عن رجل من الأنصار
أقبل معاذ من اليمن فقال يا رسول الله إني رأيت رجالا فذكر معناه

Its isnad is daif, due to the anonymity of the narrator from Muaz. But the hadith is sahih, see the previous one.
