It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) prayed while there were traces of mud on his (peace and blessings be upon him) sandals, and he (peace and blessings be upon him) had a cloak on, so he (peace and blessings be upon him) began to take care that (the mud) did not touch the cloak.
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ata except Abd al-Rahman; Abu Ali al-Hanafi is alone in narrating it."
