The Holy Quran 13:37 — Surah Ar-Ra'd
Arabic text
وَكَذَٰلِكَ أَنزَلْنَـٰهُ حُكْمًا عَرَبِيًّا ۚ وَلَئِنِ ٱتَّبَعْتَ أَهْوَآءَهُم بَعْدَ مَا جَآءَكَ مِنَ ٱلْعِلْمِ مَا لَكَ مِنَ ٱللَّهِ مِن وَلِىٍّ وَلَا وَاقٍ
Translation
Thus We have revealed it (the Qur'aan) as a special Arabic command (which suits the people and times it was revealed for, just as the previous scriptures suited the people and times they were revealed for). Surely if you follow their wishes (that you follow their religions) after knowledge (of Tauheed) has come to you, you shall have no helper nor saviour (defender) against (the punishment of) Allaah.
Tafsir (excerpt) — Tafsir Usmani
