Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrated: "It has been forbidden to drink (by putting one's mouth) from the mouth of a waterskin."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ayyub except al-Harith bin Umayr; Ibrahim al-Shafi'i is alone in narrating it."
