Musnad Abu Ya'la al-Mawsili 152:205

Muhammad ibn Yahya ibn Abi Samina narrated to us, Abdullah ibn Raja’ narrated to us, Jarir ibn Ayyub narrated to us, from al-Sha’bi, from Nafi’ ibn Burdah, from Ibn Mas’ud, that he heard the Prophet (peace and blessings of Allah be upon him) saying, while Ramadan had begun: "If the servants knew what is in Ramadan, my nation would wish that Ramadan were the entire year." A man from Khuza’ah said: "Narrate it to us." He said: "Indeed, Paradise is decorated for Ramadan from the beginning of the year to the next. When the first day of Ramadan arrives, a wind blows from beneath the Throne, causing the leaves of Paradise to rustle. The wide-eyed houris (maidens of Paradise) look at that and say: 'O Lord, appoint for us from Your servants in this month spouses whose eyes will be cooled by us and whose eyes we will be cooled by.'" He said: "There is no servant who fasts Ramadan except that he is married to a wife from the wide-eyed houris in a tent of hollowed pearl, as Allah described: 'Houris confined in pavilions' (55:72). Upon each woman of them are seventy garments, no garment of which is the color of the other. She is given seventy types of perfume, no scent of which is like the scent of the other. For each woman of them are seventy beds of red ruby, adorned with pearls. Upon each bed are seventy mattresses, their linings made of thick silk. Above the seventy mattresses are seventy couches. For each woman of them are seventy thousand handmaidens for her needs, and seventy thousand manservants. With each servant is a platter of gold containing a type of food; he finds in the last morsel of it a pleasure he does not find in the first. Her husband is given the like of that upon a bed of red ruby, wearing two bracelets of gold adorned with red ruby. This is for every day he fasted of Ramadan, in addition to the good deeds he performed."
