Jihad (struggle in the way of Allah)

ٱلَّذِينَ ءَامَنُوا۟ يُقَـٰتِلُونَ فِى سَبِيلِ ٱللَّهِ ۖ وَٱلَّذِينَ كَفَرُوا۟ يُقَـٰتِلُونَ فِى سَبِيلِ ٱلطَّـٰغُوتِ فَقَـٰتِلُوٓا۟ أَوْلِيَآءَ ٱلشَّيْطَـٰنِ ۖ إِنَّ كَيْدَ ٱلشَّيْطَـٰنِ كَانَ ضَعِيفًا

Those who believe fight in the cause of Allāh, and those who disbelieve fight in the cause of ṭāghūt. So fight against the allies of Satan. Indeed, the plot of Satan has ever been weak.
