﴿ وَلَقَدْ جِئْنَٰهُم بِكِتَٰبٍۢ فَصَّلْنَٰهُ عَلَىٰ عِلْمٍ هُدًۭى وَرَحْمَةًۭ لِّقَوْمٍۢ يُؤْمِنُونَ ﴾

“for, indeed, We did convey unto them a divine writ which We clearly, and wisely, spelled out - a guidance and a grace unto people who will believe."”

(Verily We have brought them a Scripture) Allah says: We have sent them Muhammad (pbuh) with the Qur'an (which We expound with knowledge) with knowledge from Us; it is also said that this means: We have taught it, (a guidance) from error (and a mercy) from torment (for a people who believe) in Muhammad (pbuh) and the Qur'an.
