Narrated It was narrated from ‘Ali (رضي الله عنه) that He called for a jug of water, then he said:
Where are those who say that they dislike drinking whilst standing? He took it and drank whilst standing then he did a light wudoo` and wiped over his shoes, then he said: This is the wudoo’ of the Messenger of Allah (ﷺ) for one who is pure and has not broken his wudoo’.
Narrated It was narrated that ‘Ali (رضي الله عنه) was asked about Witr and whether it was obligatory. He said:
It is not like the obligatory prayer, but it is a Sunnah that was done by the Messenger of Allah (ﷺ) and his Companions, and they continued doing it until the end of their lives.
Narrated It was narrated from ‘Ali (رضي الله عنه) that He did wudoo’ washing each part three times and he drank the water left over from his wudoo’, then he said:
I heard the Messenger of Allah (ﷺ) say: Were it not that it would be too difficult for my ummah, I would have commanded them to use the siwak every time of prayer, and I would have delayed Isha` until the first third of the night had passed, because when the first third of the night has passed. Allah may he be exalted descends to the first heaven and stays there until dawn comes, and says: Is there any asking so that he might be given? Is there anyone praying so that he might be answered? Is there any sick person asking for healing so that he might be healed? Is there any sinner asking for forgiveness, so that he might be forgiven?
A hadeeth like that of Abu Hurairah was narrated from `Ali bin Abi Talib (رضي الله عنه) from the Prophet (ﷺ) Abi Talib.
