A lot of this will really depend on how you define “practicing.” Different people practice their religions in different ways with different levels of observence. For some such people, they may be able to have a spouse of a different faith and nonetheless effectively practice their religion.
I think the OP is looking for marriages where one of the spouses is a practising Muslim.
One of my work colleagues has just informed me that her neighbours are a married couple (Muslim husband, Catholic wife). My colleague sees the wife at mass at the local Catholic church. The husband has recently been fasting for Ramadan. I suppose that makes them both “practising”.
Islam permits men to marry outside of Islam, although IIRC requires the spouse to be one of the People of the Book. Islam, contrary to Middle East politics, is a rather tolerant religion, and considered Christians and Jews to be People of the Book. This tolerance does not extend to atheists*.
However, Muslim women may not marry outside of their faith and still be considered Muslim, technically. (I suppose there may have been Muslim women who married outside their faith and continued to practice Islam but by the most rigorous standards they would not be considered Muslim.)
So there are probably countless Muslim men who have married Christians and Jews, though I can’t give you any cites. And, by the strictest definition, no Muslim women who have.
My cousin is married to a Pakistani girl from a very religious family. I guess he’s an atheist or something, she’s a muslim - to some extend. The girl’s father didn’t like it one bit, but there it is.
I know another guy married to a Pakistani girl. He’s a gode, a priest in the nordic asa-religion (odinist). The girl’s father didn’t like it one bit, but there it is - the father has grudingly accepted an invitation to come and visit them, but won’t see the husband set foot in his own home.
