Musannaf Ibn Abi Shayba 33:84

Sufyan ibn 'Uyaynah narrated to us, from 'Amr ibn Yahya ibn Ja'dah, who said: Some of the companions of the Messenger of Allah (may Allah bless him and grant him peace) visited Khabbab and said, "Rejoice, Abu 'Abd Allah, you will meet Muhammad (upon him be peace and blessings) at the Basin." He said, "How can that be, when this—pointing to the bottom and the top of the house—is here? And the Messenger of Allah (may Allah bless him and grant him peace) said to us, 'It is sufficient for one of you from the world to have the amount of a rider's provision.'"
