Correct Answer:
B. صیح حدیث
The term صیح حدیث (Sahih Hadith) refers to a Hadith that has been declared authentic and acceptable as proof by the Imams of Hadith. This classification signifies that its chain of narration is continuous, its narrators are trustworthy and precise, and it is free from any hidden defects or irregularities. Therefore, it is considered reliable for deriving Islamic rulings and beliefs.
- ضعیف حدیث (Da'if Hadith) is weak and generally not acceptable as proof.
- متروک حدیث (Matrook Hadith) is abandoned due to a narrator being accused of lying.
- مردود حدیث (Mardood Hadith) is rejected due to severe defects in its chain or text.
