It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) performed ablution washing each part once and wiped over his sandals.
This is how Rawwad bin al-Jarrah narrated it, and he is alone in narrating munkar (denounced) reports from al-Thawri, this being one of them; the reliable (thiqat) narrators narrated it from al-Thawri without this wording. It was also narrated like this from Zayd bin al-Hubab from al-Thawri, and it is not mahfuz (accurately preserved).
