Answer
Aryan can be used by Muslims, Hindus, and people from any other religion, because it is not a religious name, it is a racial name that belongs to the Indo-European races, which means all the races from Europe to Kurdistan to Persia to India.
Aryan is derived from Arya, which are words in Sanskrit, Avestan and Old Persian meaning “noble” and “excellent”. The people of ancient India and ancient Iran used Arya, Aryan, and its related words as a name for their race, which today are called the Indo-Europeans.
Aryan is not an Islamic/Arabic name, but since the meaning is good Muslims can use it. It is a common name among the Kurdish, Persian and Indo-Pakistani peoples.
