Ibn ‘Abbaas said, "The extended shade (mentioned in verse 56:30) is a tree in Paradise. Its trunk will be so long that it will take a fast horse rider 100 years to travel from one side to the other. The people of Paradise will leave their rooms and go to the shade of the tree to talk to each another. They will talk about the amusements of the world and desire them. Allaah will send a wind from Paradise which will shake this tree, causing it to recreate all the amusements of this world." (Ibn Abi Dunya) Is this authentic?

All perfect praise be to Allah, The Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad, sallallahu ‘alayhi wa sallam, is His slave and Messenger.

This report, narrated on the authority of Ibn ‘Abbaas, may Allah be pleased with him, was declared Dha‘eef (weak) by Al-Albaani in his book Dha‘eef At-Targheeb wa At-Tarheeb, vol. 2, p. 481, no. 2202.

Allah knows best.
