Definition of "mushrik"

And do not marry mushrik women until they believe, for a believing bondmaid is better than a mushrik woman, even though you may admire her.

1999, Yusuf Al-Qaradawi, quoting The Qur'an, translated by Kamal El-Helbawy, M. Moinuddin Siddiqui, Syed Shukry, and Ahmad Zaki Hammad, The Lawful and the Prohibited in Islam (Al-Halal Wal Haram Fil Islam)

A person can have committed shirk in their lifetime and still find forgiveness (especially by saying the Shahada and becoming a Muslim). The concept is that if one dies in this state (as a mushrik, an idolator, one who engages in and does not repent shirk), there is no forgiveness.
