Musnad Abu Ya'la al-Mawsili 241:2

Zuhayr narrated to us, Ibn ‘Uyaynah narrated to us, from ‘Amr, from Yahya ibn Ja‘dah, who said: Some people from the companions of the Messenger of Allah (may Allah bless him and grant him peace) visited Khabbab and said, "Rejoice, Abu ‘Abd Allah, for you will meet Muhammad (may Allah bless him and grant him peace) at the Basin (al-Hawd)." He said, "How can this be?" and he pointed to the top of the house and its bottom, "when the Messenger of Allah (may Allah bless him and grant him peace) has said: 'It is sufficient for one of you from the world like the provision of a rider.'"
