1. **Qur’an Source:** Surah Al-Baqarah, Surah 2, Ayah 6 **Arabic:** إِنَّ ٱلَّذِينَ كَفَرُوا۟ سَوَآءٌ عَلَيْهِمْ أَأَنذَرْتَهُمْ أَمْ لَمْ تُنذِرْهُمْ لَا يُؤْمِنُونَ **Translation:** Indeed, those who disbelieve — it is all the same to them whether you warn them or do not warn them; they will not believe. **Simple Meaning:** A disbeliever, in this ayah, is a person who does not believe in Allah and rejects the truth after it is shown to them. 2. The Qur’an also teaches that a person should not rush to judge others. Only Allah knows what is in each heart. 3. A simple example is this: If a teacher shows the right answer many times, but a student still says, “I do not want it,” that student is ignoring the truth. **Takeaway:** A disbeliever is someone who rejects belief in Allah and His message. We should always ask Allah to guide us and keep our hearts firm. Allah knows best.
