What is the ruling on saying "May your religion be pleased" to a non-Muslim?

It is not permissible for a Muslim to utter words that praise a religion other than Islam, or to pray for its victory and dominance, as this could lead to apostasy from Islam. The phrase "I wish your religion happiness" carries different meanings, and to judge it, one must inquire about the speaker's intent. If it is intended as a prayer for a religion other than Islam to achieve victory and prominence, then it is among the gravest of prohibitions. However, if it was said idly without intending its meaning, then it is excused, as Allah Almighty says: (And there is no blame upon you for that in which you have erred, but [blame is due for] what your hearts intended) Al-Ahzab/5. It might also be said with the intention of praying for the person himself to have happiness, with the word "religion" being an unintended, idle utterance. Therefore, a Muslim should avoid this phrase.
