Surah Al-Ahqaf — Ayah 12 (46:12)
وَمِن قَبۡلِهِۦ كِتَٰبُ مُوسَىٰٓ إِمَامٗا وَرَحۡمَةٗۚ وَهَٰذَا كِتَٰبٞ مُّصَدِّقٞ لِّسَانًا عَرَبِيّٗا لِّيُنذِرَ ٱلَّذِينَ ظَلَمُواْ وَبُشۡرَىٰ لِلۡمُحۡسِنِينَ ١٢
English translation (Saheeh International)
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.
Brief commentary
And before this Qur’ān is the Torah, the book which Allah revealed on Moses (peace be upon him) as a leader to be followed in the truth and as a mercy for those who believe in it and follow it amongst the Israelites. And this Qur’ān which has been revealed upon Muhammad (peace be upon him) is a book which confirms the books before it, in the Arabic language, so that he can warn through it those who wronged themselves through associating partners with Allah and by committing sins, and it is a glad tiding to the good-doers who made their relationship with their Creator and their relationship with His creation good.
