Sufyan (may Allah have mercy on him) narrated to us with the same chain that the Prophet (peace and blessings be upon him) wiped over the sandals. The correct version is the narration of the group. (b) Abd al-Aziz al-Darawardi and Hisham bin Sa'd narrated from Zayd bin Aslam (may Allah have mercy on him) the sprinkling of water on the foot with the sandal on it, but it is also possible that he washed the foot with the sandal on. Other narrators narrate from Zayd bin Aslam (may Allah have mercy on him) that both feet were washed. The hadith is one and the same, and a large number (of narrators) is more worthy of accurate preservation than a small number, especially given the merit of those who preserved the washing after the sprinkling over those who did not preserve it.
