Nation of islam muslims?

Y do nation of islam claim to be muslim but do not speak arabic or perform the 5 daily prayers? Y do they not read quran and believe fard muhammad or elijah muhammed as god or gods messenger. The main thing a muslim says is laa illiha illillah wa muhammada rasullullah. Why does khalid muhammed call for genocide of the white race when the word islam means peace? real islam judges bu your actions not color. do u feel that hate overcomes hate? Or do u think love overcomes hate?
