Hadith 764 Umm Thabit Kabshah
, daughter of Thabit
and the sister of Hassan bin Thabit, (the Prophet's
poet) reported: The Messenger of Allah
visited me and drank some water from a hanging water-skin while he was in a standing posture. So, I stood up and cut off the mouth (of that water-skin). [At-Tirmidhi].
An-Nawawi said that the reason why she did this was to keep to receive benediction that part of the water-skin which the lips of The Messenger of Allah
touched.
Commentary: The first two Ahadith forbid us from drinking water out of the mouth of a water-skin, whereas, once The Messenger of Allah
himself had done so. This shows that not to drink water by this way is also approved. However, if needed, it is allowable. For this reason Imam An-Nawawi clarified that to drink water out of the mouth of the water-skin is conditionally permissible and not forbidden. But to eschew it is desirable. Likewise, to receive benediction from the Prophet's
left-overs is permissible as long as this does not take the form of worship and glorification.
