Hadith.983 - Ismail ibn Muslim narrated from Imam Jafar ibn Muhammad Al-Sadiq 
from his forefathers that:
"The Messenger of Allah ﷺ was approached by a man who said:
'O’ Messenger of Allah ﷺ, I complain to you about the whispers (waswasah) I experience during my prayers, to the point that I no longer comprehend what I have prayed, whether I have added something or omitted something.'
The Messenger of Allah ﷺ responded: 'When you enter into your prayer, strike your left thigh with your right index finger, then say: "In the name of Allah (swt), and with Allah (swt), I place my trust in Allah (swt). I seek refuge with Allah (swt), the All-Hearing, the All-Knowing, from the accursed Devil."
By doing this, you will strike him and ward him off, and he will be driven away from you.'".
