I know some people who are religious but they aren't, OMG ,in which language i have to speak for you to understand.
One can be called Muslim but not religious and one can be called atheist but religious, it is about the way of life
One may live serving the poor and avoid doing bad deeds and then he has "din" or perfect way of life.
both mainstream and reformist Muslim writers take the word to mean an all-encompassing way of life carried out under the auspices of God's divine purpose as expressed in the
Qur'an and
hadith
