Christians and la ilaha illallah

[LutheranDK]

Many Muslims say this short little prayer - la ilaha illallah, “there is no god but God” - often. I’m wondering if it would be okay for me, a Christian, to pray those words, since Muslims don’t believe God is a trinity. Would a Christian who says “la ilaha illallah” be denying that God is triune, and thereby deny that Jesus is God? I think what this question might come down to is whether the title Allah can include Jesus.

No problem the way I see it. Especially not if you add “wa ashadu Yasua’dar ibn-Allah”
“And I proclaim that Jesus is God-Son”
