42:8
وَلَوۡ شَآءَ اللّٰهُ لَجَعَلَهُمۡ اُمَّةً وَّاحِدَةً وَّلٰكِنۡ يُّدۡخِلُ مَنۡ يَّشَآءُ فِيۡ رَحۡمَتِهٖؕ وَالظّٰلِمُوۡنَ مَا لَهُمۡ مِّنۡ وَّلِيٍّ وَّلَا نَصِيۡرٍ
And if Allah willed, He could have made them [of] one religion, but He admits whom He wills into His mercy. And the wrongdoers have not any protector or helper
