The ruling on a son addressing his mother by her name

Question:
After this, a message was sent by the listener (Muhammad . A), saying: My brothers, who are older than me, and I have become accustomed to calling our mother by her name, and she is pleased with that. Do we commit a sin?

Answer:
I do not know of anything that indicates a sin; I do not know of anything in that regard. However, if it is possible to address her by her kunya, "O so-and-so's mother," or "O my mother," or "O my mother," or "O my mother," that may be better in terms of etiquette. Otherwise, there is no blame. I do not know of any blame if one says, "O So-and-so," "O Fatimah," "O Noura," or "O Hafsa." There is no blame in that. But from the perspective of Islamic etiquette, it is a kindness to address her by her kunya: "O so-and-so's mother," or "O my mother," or "O my mother," and the like. This is better in terms of etiquette.
