Teach me something by which I can overcome my enemies

Sheikh Sadooq says: My father has reported on the authority of his father and Amiralmomenin (AS): *       * “On the eve of Badr Battle, I dreamt of Prophet Khadir.  I said to him: Teach me something by which I can overcome my enemies.  He said: Ya hova Ya manlahova illahova.  When morning came, I recited it for the Holy Prophet who said: O Ali! You have learnt the chief Name of God! Therefore, this “Zekr” was on my tongue on the Day of Badr.”     It has been reported that whenever Imam Ali (AS) completed reciting (say: He, Allah is One) he would recite: *        * “O our true Desire! O You besides whom there is no Desire, forgive me and help me against unbelievers.”    Imam Ali (AS) recited the same in Saffein battle and broke the rank of the enemy. Reference : Oddatud Daee
