Heart Disease (Coronary Support)

أَفَلَمْ يَسِيرُوا فِي الْأَرْضِ فَتَكُونَ لَهُمْ قُلُوبٌ يَعْقِلُونَ بِهَا أَوْ آذَانٌ يَسْمَعُونَ بِهَا ۖ فَإِنَّهَا لَا تَعْمَى الْأَبْصَارُ وَلَٰكِن تَعْمَى الْقُلُوبُ الَّتِي فِي الصُّدُورِ

"So have they not traveled through the earth and have hearts by which to reason and ears by which to hear? For indeed, it is not eyes that are blinded, but blinded are the hearts which are within the breasts."

Surah Al-Hajj · 22:46

This verse establishes the heart's anatomical location within the chest (sadr) and its vital function, foundational to understanding cardiac pathology in Islamic medicine.

إِذْ يُرِيكَهُمُ اللَّهُ فِي مَنَامِكَ قَلِيلًا ۖ وَلَوْ أَرَاكَهُمْ كَثِيرًا لَّفَشِلْتُمْ وَلَتَنَازَعْتُمْ فِي الْأَمْرِ وَلَٰكِنَّ اللَّهَ سَلَّمَ ۗ إِنَّهُ عَلِيمٌ بِذَاتِ الصُّدُورِ

"When Allah showed them to you in your dream as few; and if He had shown them to you as many, you would have lost courage and would have disputed in the matter, but Allah saved you. Indeed, He is Knowing of that within the breasts."

Surah Al-Anfal · 8:43

References cardiac courage and the physiological connection between emotional stress and chest (cardiac) response, relevant to coronary stress factors.

إِذْ جَاءُوكُم مِّن فَوْقِكُمْ وَمِنْ أَسْفَلَ مِنكُمْ وَإِذْ زَاغَتِ الْأَبْصَارُ وَبَلَغَتِ الْقُلُوبُ الْحَنَاجِرَ وَتَظُنُّونَ بِاللَّهِ الظُّنُونَا

"When they came at you from above you and from below you, and when eyes shifted and hearts reached the throats and you assumed about Allah assumptions."

Surah Al-Ahzab · 33:10

Describes acute cardiac distress syndrome with hearts reaching throats, indicating severe cardiac stress response recognized in classical Islamic cardiology.
