poster II/ Come to worship none but God
بِسمِ اللّهِ الرَّحمنِ الرَّحیم
قُلْ یَا أَهْلَ الْکِتَابِ تَعَالَوْا إِلَى کَلِمَة سَوَاء بَیْنَنَا وَ بَیْنَکُمْ أَلّا نَعْبُدَ إِلّا اللّهَ وَ لَا نُشْرِکَ بِهِ شَیْئاً وَ لَا یَتَّخِذَ بَعضُنَا بَعضاً اَربَاباً مِن دُونِ اللّهِ فَاِن تَوَلَّوا فَقُولُوا اشهَدُوا بِاَنَّا مُسلِمُونَ
Say (O Muhammad PBUH): O people of the Scripture (Jews and Christians): Come to a word that is just between us and you, that we worship none but Allah, and that we associate no partners with Him, and that none of us shall take others as lords besides Allah. Then, if they turn away, say: Bear witness that we are Muslims.
