Musannaf Ibn Abi Shayba 30:129

Waki’ narrated to us, from Ja’far ibn al-Zubayr, from al-Qasim, from Abu Umamah, regarding [the verse]: "And raised furnishings" (56:34). He said: If one were to fall from the top of a furnishing of them, he would fall for such and such years until he reached its base.
