Musannaf Ibn Abi Shayba 27:826

Isa ibn Yunus narrated to us, from Abu Bakr al-Ghassani, from Habib, who said: Ka’b said: The most beloved of lands to Allah is al-Sham, and the most beloved of al-Sham to Him is al-Quds (Jerusalem), and the most beloved of al-Quds to Him is a mountain in Nablus. A time will surely come upon the people when they will touch or wipe themselves against the mountains between them.
