Surah Ibrahim, ayah 52

14:52

هَٰذَا بَلَٰغٞ لِّلنَّاسِ وَلِيُنذَرُواْ بِهِۦ وَلِيَعۡلَمُوٓاْ أَنَّمَا هُوَ إِلَٰهٞ وَٰحِدٞ وَلِيَذَّكَّرَ أُوْلُواْ ٱلۡأَلۡبَٰبِ ٥٢

Hādhā balāghul lin-nāsi waliyundharū bihī waliya'lamū annamā huwa ilāhun wāhidun waliyaddhakkara ulul-albāb

This [Qur’ān] is notification for the people that they may be warned thereby and that they may know that He is but one God and that those of understanding will be reminded.
