The learn about the sunnah and be like the prophet (pbuh) and learn the protective dua.
I swear by Allah (swt) you will never do anything according to the sunnah except it will be opposite to the shaytan.
eg. The messenger of Allah said "Eat with your right hand because shaytan eats with his left"
"Don't sit half in the shade and half in the sun because it is the sitting of shayatn"
"Dont lie on your stomach this is the position of shaytan"
"Dont wear one shoe this is from shaytan"
"When you eat say bismillah"
"when you enter your homes say bismillah"
so really you should learn hadith and dua rather than learning about shaytan.
i can understand if you meet them face to face and have to talk to them or interact with them or give them dawah ect.
Like abu hurairah (ra).
But if you're not, just stick to the sunnah.
