Musannaf Ibn Abi Shaybah 5734 — The hour at which one should set out

Isa bin Sahl said that he saw his grandfather, Sayyiduna Rafi' bin Khadij (may Allah be pleased with him), and his sons sitting in the mosque; when the sun had risen they would pray two rak'ahs and then set out for the Eid prayer ground. They did this on both Eids, Eid al-Fitr and Eid al-Adha.
