In the Qur' an, Allah warns believers against their most important enemy as follows:
Mankind! Eat what is good and lawful on the earth. And do not follow in the footsteps of Satan. He truly is an outright enemy to you. (Surat al-Baqara: 168)
You who believe! Do not follow in the footsteps of Satan. Anyone who follows in Satan' s footsteps should know that he commands indecency and wrongdoing... (Surat an-Nur: 21)
Those who submit themselves to the temptation of Satan are those who take pleasure in disobeying Allah' s commands, because of their defiance and a false feeling of superiority. Satan' s main endeavour is to present everything Allah praises as difficult and unmanageable, and thereby, to deceive people into disobedience and the manners and attitudes that are displeasing to Allah. This is Satan' s primary method, though he succeeds in tempting only those who are arrogant and desire to be unique or superior.
Believers who are obedient and forbearing, on the other hand, always observe Allah' s commands. Founded on their commitment to Him, believers are the only group of people on whom Satan' s deceptive ploys can exert no influence. They are not lured into the false promises of Satan, but hold on to the Qur' an. When they hear an evil suggestion from Satan, they immediately seek refuge in their Lord, recognise the truth, and realise that the scheming of Satan is in vain. That is because, their only purpose in life is to earn Allah' s good pleasure and the hereafter.
They are committed to the right path, since they are aware that deviation from it for the sake of worldly pleasures would only be wronging themselves.
