﴿ هَٰذَا بَصَٰٓئِرُ لِلنَّاسِ وَهُدًۭى وَرَحْمَةٌۭ لِّقَوْمٍۢ يُوقِنُونَ ﴾

“This [revelation, then,] is a means of insight for mankind, and a guidance and grace unto people who are endowed with inner certainty.”

(This) Qur'an (is clear indication for mankind, and a guidance) from error (and a mercy) preventing from chastisement (for a folk whose faith is sure) for people who believe in Muhammad (pbuh) and the Qur'an.
