Mukhtasar Muslim

It is narrated from Sayyiduna Hudhaifah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: The Dajjal will be blind in the left eye, and will have thick hair. He will have with him a garden and a fire. So his fire will actually be a garden, and his garden will actually be fire. (The scholars have said that this too is a test from Allah Almighty for His servants, so that He may establish the truth as truth and falsehood as falsehood, then disgrace him and manifest his helplessness among the people.)
