All thoughts of Waswasa are not to make you liable as long as you do not commit an act of Kufr.

Satan will always attack us in such ways of thought and don’t let such attacks lower your trust in yourself and in your ability to hold steadfast. My advice to you is the following:

1- Spend time learning the life of the Prophet (peace be upon him)

2- Try not to be alone, keep companionship with friends that will remind you of worshiping Allah.

3- Perform as many prayers as you can in the Masjid.

4- Try to memorize new verses of the Quran.
