Musnad Ahmad 3510

It was narrated that Abut-Tufail said: I was with Mu'awiyah and Ibn '‘Abbas (رضي الله عنه) when they were circumambulating the House. Ibn 'Abbas would touch the two corners and Mu'awiyah would touch all of them. Ibn ‘Abbas (رضي الله عنه) said: The Messenger of Allah (ﷺ) only touched these two corners, the Yemeni and the Black (i.e., where the Black Stone is). Mu'awiyah said. No part of it is to be forsaken."
