Surah 14 : Ayah 52

هَـٰذَا بَلَـٰغٌ لِّلنَّاسِ وَلِيُنذَرُوا۟ بِهِۦ وَلِيَعْلَمُوٓا۟ أَنَّمَا هُوَ إِلَـٰهٌ وَٰحِدٌ وَلِيَذَّكَّرَ أُو۟لُوا۟ ٱلْأَلْبَـٰبِ

This [Qur’an] is a message for all mankind, so that they may be warned thereby and know that He is One God, and so that the people of understanding may take heed.
