A contribution from my book "WİE MİEL MUSLIM IN YOU?"
The basmala is mentioned there twice.
Is it a sin to say "Bi Iḏnillahi"?
The answer is in the Quran in the following form:
What does the Qur'an say about the “Bi iḏnillahi”?
It is written that the "Bi iḏnillahi" occurs even more often in the Koran than the "Basmala". It can be found in several forms, depending on the subject under discussion.

She replied: "If it is not written in the Koran, then you must not use it. Otherwise you will be banned from everyone." Okay, it's not actually written in the Quran, but it's not against the spirit of the Quran. Nevertheless, she stood behind her opinion and had a negative attitude towards the subject. Then I decided to write it down. If you are reading this, it means to me that I was able to address you and your intellect with this book. Now it's your turn. The ayad reads as follows:
We know that Allah is "Raḥman" and "Raḥim". Just like we pronounce it in “Basmala”:
I said it like this. Since the habit of basmala runs deep, it wasn't really difficult for me either:
