Yahya, from Abu Umayya, from al-Mutalammis al-Sadusi, from Ishaq ibn Abdullah ibn al-Harith, who said:

The Messenger of Allah (peace be upon him) said: "Uhud is a mountain that loves us and we love it, and on the Day of Resurrection, it will appear between Paradise and the Fire, and there will be detained upon it people who recognize all by their mark; they are—if Allah wills—from the people of Paradise."

Muhammad said: And every elevated place among the Arabs is [called] an a'raf.

Surat al-A'raf from verse (48) to verse (51).
