ثُمَّ جَعَلْنَاكَ عَلَىٰ شَرِيعَةٍ مِّنَ الْأَمْرِ فَاتَّبِعْهَا وَلَا تَتَّبِعْ أَهْوَاءَ الَّذِينَ لَا يَعْلَمُونَ ١٨

Then We have put you (O Muhammad SAW) on a plain way of (Our) commandment [like the one which We commanded Our Messengers before you (i.e. legal ways and laws of the Islamic Monotheism)]. So follow you that (Islamic Monotheism and its laws), and follow not the desires of those who know not. [Tafsir At-Tabari Vol. 25, Page 146].

ثُمَّ جَعَلْنَاكَ عَلَىٰ شَرِيعَةٍ مِّنَ الْأَمْرِ

Then We have put you (O Muhammad SAW) on a plain way of (Our) commandment

فَاتَّبِعْهَا

So follow you that

وَلَا تَتَّبِعْ أَهْوَاءَ الَّذِينَ لَا يَعْلَمُونَ

and follow not the desires of those who know not

إِنَّهُمْ لَن يُغْنُوا عَنكَ مِنَ اللَّهِ شَيْئًا ۚ وَإِنَّ الظَّالِمِينَ بَعْضُهُمْ أَوْلِيَاءُ بَعْضٍ ۖ وَاللَّهُ وَلِيُّ الْمُتَّقِينَ ١٩

Verily, they can avail you nothing against Allah (if He wants to punish you). Verily, the Zalimun (polytheists, wrong-doers, etc.) are Auliya' (protectors, helpers, etc.) to one another, but Allah is the Wali (Helper, Protector, etc.) of the Muttaqun (pious - see V. 2:2).

إِنَّهُمْ لَن يُغْنُوا عَنكَ مِنَ اللَّهِ شَيْئًا ۚ

وَإِنَّ الظَّالِمِينَ بَعْضُهُمْ أَوْلِيَاءُ بَعْضٍ ۖ

Verily, the Zalimun (polytheists, wrong-doers, etc.) are Auliya' (protectors, helpers, etc.) to one another,

وَاللَّهُ وَلِيُّ الْمُتَّقِينَ
