Prejudice is when you impose your own view on what God has written to turn it your own way ....... prejudice is when you hear a view that does not correspond to your own view even if the Quran states clearly that you are wrong.
Prejudice is not whether you like black, white, brown, yellow, green, Chinese, American, Arab, European, Honey, sugar, water, food, running, jogging , walking, animals, birds, the sea, the sun, the moon, the stars, your children, your wealth, your work, your friends, your family, your neighbor ... or NOT!
thats your choice as long as you do no harm intentionally and be just with them. "JUST" does NOT mean good all the time ..... as GOD has shown us several times in the past and will show us again very soon ...... so wait with patience and repel the unbelievers and the Mushrikeen with good arguments.
