762/1 - Abu Sa‘īd al-Khudri (may Allah be pleased with him) reported: “The Prophet (may Allah’s peace and blessings be upon him) forbade bending the mouths of waterskins to drink directly from them.”
[Narrated by Al-Bukhāri and Muslim]
763/2 - Abu Hurayrah (may Allah be pleased with him) reported: “The Messenger of Allah (may Allah’s peace and blessings be upon him) prohibited drinking directly from the mouth of a waterskin.” [Narrated by Al-Bukhāri and Muslim]
764/3 - Um Thābit Kabshah bint Thābit, sister of Hassān ibn Thābit, (may Allah be pleased with both of them) reported: “The Messenger of Allah (may Allah’s peace and blessings be upon him) visited me and drank from the mouth of a hanging waterskin while he was standing. So, I got up and cut off its mouth.” [Al-Tirmidhi; he classified it as Hasan Sahīh (sound and authentic)]
She cut it off to keep the part that the Prophet’s mouth touched, seek blessing therefrom, and protect it from degradation. This Hadīth is taken to point out the permissibility of doing so (drinking from the mouth of a waterskin), whereas the two previous Hadīths point out what is better and more perfect. And Allah knows best.

1) Forbiddance from tilting the mouths of waterskins and drinking from them in this state, lest there are harmful things in the water.
2) This forbiddance pertains to the act of putting one’s mouth over the waterskin’s mouth, for this causes stench in the vessel. But there is nothing wrong if a person pours water from the skin and then drinks it.
3) It is permissible to drink while standing, if needed. In such a case, a person does what is otherwise forbidden, because of need.
4) It is permissible to seek blessing from the Prophet’s authentic relics. The Companions (may Allah be pleased with them) were keen to retain his relics and belongings to seek blessing therefrom. As for other people, no blessing should be sought from their bodies or relics. This trait exclusively belongs to the Prophet (may Allah’s peace and blessings be upon him) in light of his status as a Messenger of Allah.
