Your Lord has decreed that you worship none but Him, and that you be kind to parents. Whether one or both of them attain old age in your life, say not to them a word of contempt, nor repel them, but address them in terms of honor. There is no place in a Muslim's heart for racial, national, gender, or other prejudices. There is One Creator, and we are all His creation. The diversity of human life is one of the Signs of Allah, part of the beauty of His creation, and something to be admired and respected.
Righteousness is the only distinguishing factor among people.
We have created you from a male and a female, and made you into nations and tribes so that you may know one another. Verily, the most honored among you in the sight of Allah is the one who is the most righteous. We must not abuse or speak ill of other religious leaders, nor say anything insulting. We must not seek dissention unnecessarily, but live in peace and amity. Muslims are encouraged to seek good relations especially with them, as they have more in common than with the pagans or atheists.
