How to fight Whims and Evil Thoughts

You can fight Whims and Evil thoughts by practicing the following supplications twice a day every day for just 10 times each.
اَعُوْذُباِللہِ مِنَ الشَّيْطنِ الرَّجِيْم
بِسْمِ اللہِ الرَّحمنِ الرَّحِيْم
لَاحَوْلَ وَلَا قُوَّةَ اِلَّا بِاللہِ الْعَلِىِّ الْعَظِيْم

And whenever you feel a whim or an evil thought, just recite it again for ten times again.
