What is the ruling on repeating a single prayer several times due to feeling hypocritical when performing it with tranquility, and does that affect the ablution?

Tranquility (ṭumaʾnīnah) is an obligatory element of prayer, and excessive haste that compromises it invalidates the prayer. The questioner must cast away these whisperings (waswasah) and know that they are from Satan. She should pray with tranquility and not repeat the prayer after performing it. She must maintain the regular Sunnah (definition) prayers and not pay attention to whisperings of showing off (riyāʾ).
