وَلَقَدْ جِئْنٰهُمْ بِكِتٰبٍ فَصَّلْنٰهُ عَلٰى عِلْمٍ هُدًى وَّرَحْمَةً لِّقَوْمٍ يُّؤْمِنُوْنَ

Wa laqad ji'nāhum bikitābin faṣṣalnāhu ‘alā ‘ilmin hudaw wa raḥmatal liqaumiy yu'minūn(a).

"And We had certainly brought them a Book which We detailed by knowledge - as guidance and mercy to a people who believe."
