Is it permissible to congratulate Christians on Easter by saying: "The love of Christ is common among us And He is the righteous, blessed messenger, a word from God in the pure Virgin The honorable and prominent in this world and the hereafter. I love you very much and wish you well"?

If the message is presented on a Christian holiday, it is a congratulation that is impermissible, regardless of its content. Christ, in the view of Muslims, is a righteous and blessed messenger, whereas in the view of Christians, he is the son of God. This is a disbelieving tenet that necessitates detesting its proponent and disavowing it, not loving it, as stated in the Holy Quran in Surah At-Tawbah, Al-Ma'idah, and Al-Jinn.
