:|: Islam – the Supreme Way of Life :|:
:|: Consequence of FOLLOWING Kuffar’s Deen :|:

وَلَن تَرْضَىٰ عَنكَ الْيَهُودُ وَلَا النَّصَارَىٰ حَتَّىٰ تَتَّبِعَ مِلَّتَهُمْ ۗ قُلْ إِنَّ هُدَى اللَّهِ هُوَ الْهُدَىٰ ۗ وَلَئِنِ اتَّبَعْتَ أَهْوَاءَهُم بَعْدَ الَّذِي جَاءَكَ مِنَ الْعِلْمِ ۙ مَا لَكَ مِنَ اللَّهِ مِن وَلِيٍّ وَلَا نَصِيرٍ

And never will the Jews or the Christians approve of you until you follow their MILLAT (‘Way of LIfe’/LifeStyle). Say, “Indeed, the guidance of Allah is the [only] guidance.” If you were to follow their desires after what has come to you of knowledge, you would have against Allah no protector or helper.

ইহুদী ও খ্রীষ্টানরা কখনই আপনার প্রতি সন্তুষ্ট হবে না, যে পর্যন্ত না আপনি তাদের জীবন ব্যাবস্থার অনুসরণ করেন। বলে দিন, যে পথ আল্লাহ প্রদর্শন করেন, তাই হল সরল পথ। যদি আপনি তাদের আকাঙ্খাসমূহের অনুসরণ করেন, ঐ জ্ঞান লাভের পর, যা আপনার কাছে পৌঁছেছে, তবে কেউ আল্লাহর কবল থেকে আপনার উদ্ধারকারী ও সাহায্যকারী নেই।

Bismillah! Al Hamdulillah!
Wa AsSalatu AsSalamu A’ala Rasulallah!

En Shaa Allah, we will do Critical Reasoning of the part of this Ayah.

2. ‘Say, Allah’s GUIDANCE is the ONLY Guidance.’

What’s the guidance for?
Guidance is for Ebadah,
Guidance is for the systems of life/’ways of life’

3. ‘But if you are to follow their ways (Hawa) after this guidance (this way of life).’

Here Allah mentions it as their ‘HAWA’, meaning desire.
Which means, their ways of life is designed from their desires (Hawa), whatever their heart desires, whatever they think is ‘best’, because they left the ways of their creator long back.
So, Allah Subhanahu clearly warned you that if you follow their ways,

4. ‘Then you won’t find anybody to help you against Allah.’

What does this mean?
Following Kuffar’s Deen means you are destroyed, you made Allah angry.
There will be no help for you in the Qabr, nor in the Qiyamah!

Wa Allahu A’lam.
May Allah protect us from following Kuffar’s Deen.
May Allah help us, save us from the punishment in Qabr and on the Qiyamah!
Ameen.
