Two more weapons that, according to the Prophet of Allah (a.s.), are most effective in defeating Satan are: Sincere obedience of Allah and steadfastness in doing good deeds. It is a Jehad e Akbar when a person, just for the sake of Allah and His friendship, ignores his personal profits and gains. This is better than the Jehad fought with the infidels because this is confrontation with Nafs e Ammara or the vile personal instincts. If one fails in this Jehad, he may not succeed in the other! The cause of the defeat will definitely be the instigation and temptation by Satan. In this defeat the person will not only die but also be given retribution in the Hereafter.
Hazrat Syed e Sajjad (a.s.) says in one of his supplications, " O Allah! I seek you protection from my enemy! O Master of the House! The ferocious dog is attacking me. Come to my rescue and save me from the harm that it can cause to me!"
