Correct Answer:
C. حسن اخلاق
The question asks what will be the heaviest thing in the book of deeds on the Day of Judgment. According to Islamic teachings, حسن اخلاق (good manners or excellent character) holds immense weight.
- The Prophet Muhammad (PBUH) said, "There is nothing heavier in the scales than good character." This emphasizes its paramount importance.
- While نماز (prayer) and حج (Hajj) are fundamental pillars of Islam and carry great reward, the Hadith specifically highlights good character as the heaviest.
- حقوق العباد (rights of people) are also crucial and are often intertwined with good character, as treating others justly and kindly is a manifestation of good manners. However, "good character" is a broader concept that encompasses these rights and more.
