Musannaf Ibn Abi Shayba 27:352

'Abdah bin Sulayman and Abu Usamah narrated to us, from Mis'ar, from 'Abd al-Malik bin Maysarah, from Mus'ab bin Sa'd, from Mu'adh bin Jabal, who said: "Indeed, 'Umar is in Paradise. And the Messenger of Allah (may Allah bless him and grant him peace) said: 'While I was in Paradise, I saw a house in it, so I said: "Whose is this?" It was said: "For 'Umar bin al-Khattab."'"
