Sunan Ibn Majah, Chapter: The Chapters on Ascetism (Zuhd)

"We came back (from a campaign) with the Messenger of Allah (saw) and he said: By the One in Whose Hand is the soul of Muhammad, there is no person who believes then stands firm, but he will be caused to enter Paradise. I hope that they will not enter it until you and those who are righteous among your offspring will enter it and take up your dwelling places therein. And my Lord has promised me that seventy thousand of my nation will enter Paradise without being brought to account."
