The final divine message encompasses all the previous divine messages. We believe in them all. Thus, we do not reject the Christians as they are people of the book. Allah U has said: ﴾شَرَعَ لَكُمْ مِنْ الدِّينِ مَا وَصَّى بِهِ نُوحاً وَالَّذِي أَوْحَيْنَا إِلَيْكَ وَمَا وَصَّيْنَا بِهِ إِبْرَاهِيمَ وَمُوسَى وَعِيسَى أَنْ أَقِيمُوا الدِّينَ وَلا تَتَفَرَّقُوا فِيهِ ﴿
“He has ordained for you of religion what He enjoined upon Noah and that which We have revealed to you, [O Muhammad], and what We enjoined upon Abraham and Moses and Jesus – to establish the religion and not be divided therein.” [Surah Asy-Syuraa: 13].
Therefore, every call containing separatism in the name of religion is invalid and religion is free of it. This is because, the religion gathers and does not separate as Allah is One and He was The One who sent Ibraham u, Musa u, Isa u and concluded them with the leader of the Messengers, Muhammad r.
﴾وَبِالآخرَةِ هُمْ يُوقِنُونَ﴿
“and of the Hereafter they are certain [in faith].”
