What is the ruling on performing ablution for every prayer if the previous ablution was not invalidated?

Prayer is one of the pillars of Islam, and it has conditions, among them purity by removing both minor and major ritual impurity. Minor ritual impurity is removed by performing ablution (wudu') before each prayer, for Allah Almighty says: "O you who have believed, when you rise to [perform] prayer, wash your faces and your forearms to the elbows and wipe over your heads and wash your feet to the ankles." If a person has performed ablution and their ablution has not been invalidated by any of the nullifiers (anything exiting from the two private parts, sleep, eating camel meat), then they are not required to repeat ablution. The Prophet, peace and blessings be upon him, prayed the five prayers on the day of the conquest of Mecca with a single ablution.
