The racism Racism is a sensitive subject especially in our time, but exactly what's the meaning of racism . the racism is the belief that another person is less than human -- because of skin color, language, customs, place of birth, religion or any factor that supposedly reveals the basic nature of that person. In the religion of Islam there is no racism because all people are equal . The messenger of Allah, Muhammad said: لا فرق بين عربي و لا أعجمي و لا أبيض ولا أسود إلا بالتقوى" حديث شريف" it means that there is no difference between Arabic and not Arabic People and between white or black person, but except in piety.( believing in god and doing good deeds and to move away from evil deeds , Obedience to Allah ....) It is shortly the view of el Islam about racism ,so what do you think about racism?
