Is the common information true that saying "أنا فاطر" (Ana Fatir - I am fasting) is considered polytheism (shirk) because the word "فاطر" (Fatir) exists in the Holy Quran meaning "Creator," and that the correct phrase to say is "أنا مفطر" (Ana Mufṭir - I am one who breaks the fast/I am not fasting)? And is there conclusive legal evidence for this, and what is the opinion of scholars on this issue?

A Muslim should be careful about the words he utters, keen on safeguarding his belief, by learning matters of Tawhid and correct creed. It is not permissible to declare a person a disbeliever without sound evidence. The word "faṭara" has multiple meanings in the Arabic language, including creation, origination, and splitting. So, al-Fāṭir can mean the Creator, the Originator, or one who splits something. It can also mean one who ate or drank in the context of fasting. Based on this, it is not permissible to rule that someone is committing shirk if they say "I am faṭir" intending the opposite of fasting or that they have begun their work. Similarly, one does not disbelieve if they describe a person with attributes that are shared in the language between the Creator and the created, such as "generous" (karīm), "great" (ʿaẓīm), or "merciful" (raḥīm), because the Holy Quran also used these attributes to describe created beings.
