The Messenger of Allah ﷺ said, "Isa son of Maryam will descend as a just leader and an equitable judge. He will break the cross, kill the swine, restore peace, and turn swords into sickles. The venom of every venomous creature will be removed. The sky will send down its provision, and the earth will bring forth its blessings, until a child will play with a serpent and it will not harm him, the wolf will tend the sheep without harming them, and the lion will tend the cattle without harming them."
حدثنا سريج قال حدثنا فليح عن الحارث بن فضيل الأنصاري عن زياد بن سعد
قال رسول الله ﷺ ينزل عيسى ابن مريم إماما عادلا وحكما مقسطا فيكسر الصليب ويقتل الخنزير ويرجع السلم ويتخذ السيوف مناجل وتذهب حمة كل ذات حمة وتنزل السماء رزقها وتخرج الأرض بركتها حتى يلعب الصبي بالثعبان فلا يضره ويراعي الغنم الذئب فلا يضرها ويراعي الأسد البقر فلا يضرها

Its isnad is sahih. There is much discussion regarding whether Ziyad bin Saad heard from Abu Hurairah, but he narrates from those even earlier than him. The hadith has already appeared at 2/437.
