What is the Shari'ah term used for congratulating on the festival? And when is it said on the day of the festival?

The questioner : Well, regarding the festival congratulation, why is the phrase "May you be well every year" not used?

The Shaykh : Because it is the congratulation of the disbelievers, and we have been commanded to differ from them first. Second: We have a transmitted congratulation: "May Allah accept your obedience."

The questioner : Regarding this question, when is this said?

The Shaykh : It is said on 'Id al-Fitr.

The questioner : Only, meaning immediately after the prayer? Or at the first meeting between Muslims?

The Shaykh : This is only on the festival.

The questioner : The first meeting takes place on the festival.

The Shaykh : This is usually done after the prayer... meaning.

The questioner : And if a meeting occurs on the second or third day of Fitr.

The Shaykh : There are no days of the festival; the festival is one.

The questioner : I mean in the days of Shawwal, if I meet my brother in the mosque on the second day of Shawwal, can I say it to him?

The Shaykh : You can, on the condition that the intention is the transition from fasting to breaking the fast.
