ٱلْأَحْقَاف : ١٢

  • وَمِن And before it
  • قَبۡلِهِۦ And before it
  • كِتَٰبُ (was the) Scripture
  • مُوسَىٰٓ (of) Musa
  • إِمَامٗا (as) a guide
  • وَرَحۡمَةٗۚ and a mercy
  • وَهَٰذَا And this
  • كِتَٰبٞ (is) a Book
  • مُّصَدِّقٞ confirming
  • لِّسَانًا (in) language
  • عَرَبِيّٗا Arabic
  • لِّيُنذِرَ to warn
  • ٱلَّذِينَ those who
  • ظَلَمُواْ do wrong
  • وَبُشۡرَىٰ and (as) a glad tidings
  • لِلۡمُحۡسِنِينَ for the good-doers
And before it was the scripture of Moses to lead and as a mercy. And this is a confirming Book in an Arabic tongue to warn those who have wronged and as good tidings to the doers of good.
Yet before it, that is, [before] Al-Qur'an, [there was] the Book of Moses, that is, the Torah, as a guidepost and a mercy, for those who believed in it (imaaman wa-rahmatan are two circumstantial qualifiers) and this, Qur'aan, is a Book that confirms, scriptures before it, in the Arabic tongue (lisaanan 'arabiyyan is a circumstantial qualifier referring to the subject of musaddiqun, 'that confirms') to warn those who do wrong, the idolaters of Mecca, and, it is, good tidings for the virtuous, the believers.
