Ibn Abi Najih narrates from his father that Abu Sa'id al-Khudri (may Allah be pleased with him) came to us and performed tawaf after the morning prayer. We watched to see whether he would pray or not. Abu Sa'id al-Khudri (may Allah be pleased with him) remained seated until the sun rose; then he prayed.
