Musannaf Ibn Abi Shaybah

Hazrat Ikrimah narrates that Hazrat Sa’d said: When you perform ablution once, continue to pray with that ablution until it is broken. And Hazrat Ali (may Allah be pleased with him) referred to a verse of the Holy Qur’an and said: When you intend to pray, wash your faces and your hands.

Hazrat Ibn Sirin states that the Rightly Guided Caliphs used to perform a separate ablution for each prayer.

Muhammad says that Hazrat Abu Bakr, Hazrat Umar, and Hazrat Uthman used to perform a separate ablution for each prayer. If they were in the mosque, they would have a basin brought to them.
