The questioner : What is the ruling on delivering sermons to the bride at weddings for the women, by one of the sisters, especially if she sees a widespread evil among the women, such as the use of incense? Some sisters organize a program for their weddings that includes hymns and competitions. What is your opinion on that?

The Shaykh : There is no doubt that performing such a sermon or this reminder, if the occasion exists, is an obligatory matter. However, making that a regular practice is not permissible, because it falls under the category of religious innovation.
