Surah Fussilat, Verse 6

قُلۡ إِنَّمَآ أَنَا۠ بَشَرٞ مِّثۡلُكُمۡ يُوحَىٰٓ إِلَيَّ أَنَّمَآ إِلَٰهُكُمۡ إِلَٰهٞ وَٰحِدٞ فَٱسۡتَقِيمُوٓاْ إِلَيۡهِ وَٱسۡتَغۡفِرُوهُۗ وَوَيۡلٞ لِّلۡمُشۡرِكِينَ٦

qul innamā anā basharun mith'lukum yūḥā ilayya annamā ilāhukum ilāhun wāḥidun fa-is'taqīmū ilayhi wa-is'taghfirūhu wawaylun lil'mush'rikīna

Say, [O Muḥammad], "I am only a man like you to whom it has been revealed that your god is but one God; so take a straight course to Him and seek His forgiveness." And woe to those who associate others with Allāh
