Quran Fussilat 41:6
قُلۡ إِنَّمَآ أَنَا۠ بَشَرٞ مِّثۡلُكُمۡ يُوحَىٰٓ إِلَيَّ أَنَّمَآ إِلَٰهُكُمۡ إِلَٰهٞ وَٰحِدٞ فَٱسۡتَقِيمُوٓاْ إِلَيۡهِ وَٱسۡتَغۡفِرُوهُۗ وَوَيۡلٞ لِّلۡمُشۡرِكِينَ ٦
Translation
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 –
