In another such tradition, Ali was once reciting a sermon in the city of Kufah, when Ash'as ibn Qays, a commander in the Arab army protested, "Amir-al-Momeneen! These Iranians are excelling the Arabs right in front of your eyes and you are doing nothing about it!" He then roared, "I will show them who the Arabs are!" Ali immediately retorted, "While fat Arabs rest in soft beds, the Iranians work hard on the hottest days to please God with their efforts. And what do these Arabs want from me? To ostracize the Iranians and become an oppressor! I swear by the God that splits the nucleus and creates Man, I heard the prophet once say, just as you strike the Iranians with your swords in the name of Islam, so will the Iranians one day strike you back the same way for Islam."
