It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that he said: "Drinking (water) directly from the mouth of a waterskin has been forbidden."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ayyub (may Allah have mercy on him) except al-Harith bin Umayr (may Allah have mercy on him), and Ibrahim bin Muhammad al-Shafi'i (may Allah have mercy on him) is alone in transmitting it."
