What potential consequences might I face by choosing not to embrace Islam?
Those who refuse to embrace Islam would forfeit the opportunity to acquire the greatest knowledge, which is knowing Allah and gaining insights about Him. Additionally, they would lose faith in Allah, Who grants security, tranquility, and peace of mind in this life, as well as the promise of eternal bliss in the Hereafter.
Furthermore, they would miss out on the profound teachings as well as faith in the most revered book that Allah has sent to humanity, the Honorable Qur'an.
The rejection of Islam would also lead to the denial of faith in the esteemed Prophets of Allah and the prospect of companionship with them in Paradise on the Day of Judgment. Conversely, they would find themselves in the company of devils, wicked individuals, and tyrants in Hellfire—what an evil dwelling and evil companionship!
To emphasize this, Allah Almighty says,
قُلْ إِنَّ الْخَاسِرِينَ الَّذِينَ خَسِرُوا أَنْفُسَهُمْ وَأَهْلِيهِمْ يَوْمَ الْقِيَامَةِ أَلا ذَلِكَ هُوَ الْخُسْرَانُ الْمُبِينُ (15)لَهُمْ مِنْ فَوْقِهِمْ ظُلَلٌ مِنَ النَّارِ وَمِنْ تَحْتِهِمْ ظُلَلٌ ذَلِكَ يُخَوِّفُ اللَّهُ بِهِ عِبَادَهُ يَا عِبَادِ فَاتَّقُونِ } ."So, worship whatever you wish besides Him." Say, "Indeed, the losers are those who will lose themselves and their families on the Day of Resurrection. That is indeed the clear loss.* They will have layers of fire above them and below them. That is how Allah threatens His slaves. Then fear Me, O My slaves."
[39: 15,16].
