Musannaf Ibn Abi Shayba 8:1285

Abu Bakr narrated to us, he said: Abbad bin al-Awwam narrated to us, from Yahya bin Sa’id, from Abd al-Rahman bin al-Qasim, from his father, that he used to arrive in Mecca, then perform Tawaf, then return and take a midday nap (qaylulah). Then, when it was late afternoon, he would set out and perform Sa’i between al-Safa and al-Marwa.
