Musannaf Ibn Abi Shayba 30:161

Affan narrated to us, he said: Sulayman ibn al-Mughirah narrated to us, he said: Humayd ibn Hilal said: It was mentioned to us that when a man enters Paradise, he is given the form of the people of Paradise, he is clothed in their clothing, and he is adorned with their adornment. He sees his wives, his servants, and his dwellings in Paradise, and he is seized by such a joy that if it were appropriate for him to die, he would have died. He said: Then it is said, "Do you see this joy of yours? It shall remain for you forever."
