Musannaf Ibn Abi Shayba 30:156

Al-Fadl ibn Dukayn narrated to us, from Abu Qudamah, from Abu Imran al-Jawni, from Abu Bakr ibn Abdullah ibn Qays, from his father, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "The gardens of Firdaws are four: two of gold, their ornaments, their vessels, and what is in them; and two of silver, their ornaments, their vessels, and what is in them. And there is nothing between the people and their looking at their Lord except the mantle of pride upon His Face."
