Whenever Imam Ali (a) faced an enemy he invoked Allah in the following words.
O Lord! Our hearts seek Your Protection, our faces turn to You, our eyes look towards You, our feet move towards Your path and our bodies sincerely submit to Your command. O Lord! Hidden hostilities and concealed spite are exposed, hearts are boiling over with envy and malice. O Lord! We place before You our difficulties, the absence of the Holy Prophet (s) from amongst us, the abundance of enemies, the disappointments and frustrations which face us. O Lord! Let truth prevail and let our people realize justice, honesty and piety of our case.
