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. Then he said:
'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'."
