Musannaf Ibn Abi Shayba 1:1436

1436. Isa ibn Yunus narrated to us, from al-Taymi, who said: I asked Tawus about a wound that is on a man’s face or on some part of his body, upon which there is medicine and a rag. He said: If he fears [harm], he should wipe over the rag. And if he does not fear [harm], he should remove the rag.
