Narrated Anas ibn Malik said (may Allah be well pleased with him):
"The Prophet (Allah bless him and give him peace) used to breathe into the vessel three times when he drank, and he would say: 'It is more wholesome and more thirst-quenching!’”
حَدَّثَنَا ابْنُ أَبِي عُمَرَ، قَالَ: حَدَّثَنَا سُفْيَانُ، عَنْ يَزِيدَ بْنِ يَزِيدَ بْنِ جَابِرٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي عَمْرَةَ، عَنْ جَدَّتِهِ كَبْشَةِ، قَالَتْ: دَخَلَ عَلَيَّ النَّبِيُّ صلى الله عليه وسلم فَشَرِبَ مِنْ قِرْبَةٍ مُعَلَّقَةٍ قَائِمًا، فَقُمْتُ إِلَى فِيهَا فَقَطَعْتُهُ.
Narrated 'Abd ar-Rahman ibn Abi 'Amra said that his grandmother Kabsha said:
"The Prophet (Allah bless him and give him peace) entered my presence, then he drank from a suspended waterskin while standing, so I reached up to its mouth and cut it loose.”
Narrated An-Nazzal ibn Sabra said;
"Ali (may Allah be well pleased with him) brought a jug of water, while he was in ar-Rahba, after which he dipped out a handful, washed his hands, rinsed his mouth, snuffed up his nostrils, and wiped his face, his forearms and his head. Then he drank from it while standing.:
'This is the minor ritual ablution of someone who has not excreted any substance that would render him ritually impure. I saw Allah’s Messenger (Allah bless him and give him peace) act in this manner'."
