Allah said, …“When you stand for (intend to offer) the Salah,” Allah commanded performing Wudu’ for the prayer. This is a command of obligation in the case of impurity, and in the case of purity, it is merely a recommendation. It was said that in the beginning of Islam, Muslims had to perform Wudu’ for every prayer, but later on, this ruling was abrogated.
Imam Ahmad bin Hanbal recorded that Sulayman bin Buraydah said that his father said, “The Prophet used to perform Wudu’ before every prayer. On the Day of Victory, he performed Wudu’ and wiped on his Khuffs and prayed the five prayers with one Wudu’. `Umar said to him, `O Messenger of Allah! You did something new that you never did before.’
The Prophet said, “I did that intentionally O `Umar!”
Muslim and the collectors of the Sunan also recorded this Hadith. At-Tirmidhi said,”Hasan Sahih.”
Ibn Jarir recorded that Al-Fadl bin Al-Mubashshir said, “I saw Jabir bin `Abdullah perform several prayers with only one Wudu’. When he would answer the call of nature, he performed Wudu’ and wiped the top of his Khuffs with his wet hand. I said, `O Abu `Abdullah! Do you do this according to your own opinion’ He said, `Rather, I saw the Prophet do the same thing. So, I do what I saw the Messenger of Allah doing.”’ Ibn Majah also recorded this Hadith.
