What is the one thing shaytaan will always try to do and never give up on? The Prophet (pbuh) said shaytaan will not give up on making our brothers and sisters fight between each other. The shaytaan even did this to the Companions against the Prophet (pbuh).

The shaytaan is able to create negative thoughts so well ,we think they are our own thoughts and act upon it. If he can make the Companions (ra) think negative thoughts then he also makes us think bad thoughts about our spouse, our parents, our in-laws and our friends also.  

Alhamdulillah Allah (swt) has given us tools to defeat these thoughts.
