The Pleading Woman - 58:9 O you who believe, when you meet in secret, do not speak for sin, enmity and rebellion against the Messenger, but speak for goodness and virtue. Listen to Allah, before Whom you will be gathered.
When the believers meet, they speak for good and virtue:
The Family Of Imran/3:110 You are the best community for the people. You exhort to good and forbid evil and believe in Allah. It would have been good for the people of the Book if they had believed. Most of them have gone astray, though there are some among them who believe.
The Family Of Imran/3:114 They believe in Allah and the Last Day, and they exhort to good and forbid evil and do good deeds. They are of the righteous.
The Family Of Imran/3:115 None of their good deeds will go unrequited. Allah knows the righteous very well.

The Repentance/9:71 The believing men and the believing women are friends of one another. They enjoin good, forbid evil, observe the prayer, pay the zakat, and follow Allah and His messenger. Allah will have mercy on them. Allah is Superior, Wise.
The Repentance/9:111 Allah has purchased the lives and property of the believers for Paradise. They fight and kill and are killed in the Way of Allah. This is His promise in the Torah, the Gospel and the Qur´an. Who better than Allah can fulfill His promise? So rejoice in this exchange. This is the greatest success.
The Repentance/9:112 They are: Those who repent, serve, praise, are active, bow down, prostrate, advocate good, forbid evil, and uphold the laws of Allah. Give glad tidings to those who believe.

The Pilgrimage/22:41 Those who, when We have made them rulers over the earth, observe the prayer, pay the zakat, enjoin what is good and forbid what is evil. The final decision belongs to Allah.

Luqman/31:17 "My dear son, observe prayer, enjoin good, forbid evil, and be patient with what befalls you. These are the basic behaviors."
