Al-Hujurat

O you who have believed, let not a people ridicule [another] people; perhaps they may be better than them; nor let women ridicule [other] women; perhaps they may be better than them. And do not insult one another and do not call each other by [offensive] nicknames. Wretched is the name [i.e., mention] of disobedience after [one's] faith. And whoever does not repent - then it is those who are the wrongdoers.

O you who have believed, avoid much [negative] assumption. Indeed, some assumption is sin. And do not spy or backbite each other. Would one of you like to eat the flesh of his brother when dead? You would detest it. And fear Allāh; indeed, Allāh is Accepting of Repentance and Merciful.

O mankind, indeed We have created you from male and female and made you peoples and tribes that you may know one another. Indeed, the most noble of you in the sight of Allāh is the most righteous of you. Indeed, Allāh is Knowing and Aware.

The bedouins say, "We have believed." Say, "You have not [yet] believed; but say [instead], 'We have submitted,' for faith has not yet entered your hearts. And if you obey Allāh and His Messenger, He will not deprive you from your deeds of anything. Indeed, Allāh is Forgiving and Merciful."

The believers are only the ones who have believed in Allāh and His Messenger and then doubt not but strive with their properties and their lives in the cause of Allāh. It is those who are the truthful.

Say, "Would you acquaint Allāh with your religion while Allāh knows whatever is in the heavens and whatever is on the earth, and Allāh is Knowing of all things?"

They consider it a favor to you that they have accepted Islām. Say, "Do not consider your Islām a favor to me. Rather, Allāh has conferred favor upon you that He has guided you to the faith, if you should be truthful."

Indeed, Allāh knows the unseen [aspects] of the heavens and the earth. And Allāh is Seeing of what you do.
