All perfect praise be to Allaah, The Lord of the worlds. I testify that there is none worthy of worship except Allaah and that Muhammad is His slave and Messenger.
What you say to yourself, that you will do the prayer again later, does not have any effect on the validity of your prayers; rather, your prayers in this case are valid, and you are not obliged to repeat them after that.
Therefore, we advise you to neglect and avoid these whisperings and not pay any attention to them.
You should perform your ablution normally and not repeat it, no matter how much the devil whispers to you that your ablution is not valid.
Also, do not pay any attention to these whisperings that you passed wind; rather, you should rely on the fact that you did not pass any wind.
When you pray, pray only once, and do not interrupt your prayer or repeat it after finishing it regardless of how many times the devil whispers to you that there is something wrong with your prayer.
If you act on this and follow our advice, then you will not experience these whisperings again, Allaah willing.
Allaah knows best.
