Tafsir of Surah Ar-Ra'd 13:36
﴿وَالَّذِينَ آتَيْنَاهُمُ الْكِتَابَ يَفْرَحُونَ بِمَا أُنزِلَ إِلَيْكَ وَمِنَ الْأَحْزَابِ مَن يُنكِرُ بَعْضَهُ قُلْ إِنَّمَا أُمِرْتُ أَنْ أَعْبُدَ اللَّهَ وَلَا أُشْرِكَ بِهِ إِلَيْهِ أَدْعُو وَإِلَيْهِ مَآبِ﴾
Translation of the meaning
And [the believers among] those to whom We have given the [previous] Scripture rejoice at what has been revealed to you, [O Muḥammad], but among the [opposing] factions are those who deny part of it [i.e., the Qur’ān]. Say, "I have only been commanded to worship Allāh and not associate [anything] with Him. To Him I invite, and to Him is my return."
