Musnad Ahmad 27:1491

Surayj narrated to us, Abdullah narrated to us, from Nafi’, from Ibn Umar, that he used to dye his beard yellow, wear Sabtiyyah sandals, touch the two corners [of the Kaaba], and recite the Talbiyah when his riding beast stood upright with him. And he would report that the Prophet, peace and blessings of Allah be upon him, used to do that.
