Imam عليه السلام said: "A man performed ablution and prayed. The Messenger of Allah سبحانه وتعالى, peace be upon him and his family, said to him: 'Repeat your prayer and your ablution.' So he did. Then he performed ablution and prayed again, but the Prophet صلى الله عليه وعلى آله وسلم, said: 'Repeat your ablution and your prayer.' He did so again, performed ablution, and prayed, but the Prophet صلى الله عليه وعلى آله وسلم, said: 'Repeat your ablution and your prayer.' The man then approached the Commander of the Faithful عليه السلام, and complained about this. The Commander of the Faithful عليه السلام asked him: 'Did you mention Allah’s سبحانه وتعالى name when you performed ablution?' He replied: 'No.' The Commander of the Faithful عليه السلام said: 'Then mention Allah’s سبحانه وتعالى name during your ablution.' The man mentioned Allah’s سبحانه وتعالى name, performed ablution, and prayed. When he came to the Prophet صلى الله عليه وعلى آله وسلم, and (this time) Prophet صلى الله عليه وعلى آله وسلم did not instruct him to repeat it."
