people of the book do not exaggerate your religion. do not say about allah except the truth. indeed the messiah jesus son of mary is only a messenger of allah and his word which he gave to mary and a spirit by him. so believe in allah and his messengers and do not say trinity. refrain it is better for you. allah is only one god. exaltations to him that he should have son! to him belongs all that is in the heavens and in the earth it is sufficient that allah is the guardian.
يا أهل الكتاب لا تغلوا في دينكم ولا تقولوا على الله إلا الحق إنما المسيح عيسى ابن مريم رسول الله وكلمته ألقاها إلى مريم وروح منه فآمنوا بالله ورسله ولا تقولوا ثلاثة انتهوا خيرا لكم إنما الله إله واحد سبحانه أن يكون له ولد له ما في السماوات وما في الأرض وكفى بالله وكيلا
