The Ruling on Congratulating One Another on the Occasion of the Festival

Question:
The reasons for the eclipse prayer.

Answer:
Mention of the thief. This is a matter people ask about frequently, which is congratulating one another on the occasion of the festival, 'Id al-Fitr and 'Id al-Adha. It says: There is nothing wrong with saying to his brother, "May Allah accept it from you and from us." There is nothing wrong with saying to his brother, "May Allah accept it from me," and he responds to him with the like of that. And Imam Ahmad (may Allah have mercy on him) says: I do not initiate it, but if someone initiates it with me, I respond to him.
So congratulating one another on the festival is permissible or recommended, for the sake of supplicating for acceptance, or "May Allah return it to us and to you," or "May Allah bestow upon us and upon you," and the like of that, because of what it contains of making hearts glad among the Muslims, and because of what it contains of some of them supplicating for others, so there is nothing wrong with it. Yes.
