Concept:Hadith are grouped by scholars into grades based on the reliability of their chain of narrators and text.
Explanation:The recognised classifications of Hadith include sahih, daif, and mawdu.
Sahih refers to an authentic hadith with an unbroken chain of trustworthy narrators.
Daif refers to a weak hadith that has some flaw in its chain or in the narrators.
Mawdu refers to a fabricated hadith that is falsely attributed to the Prophet Muhammad (SAW).
Another accepted grade is hasan, which means a good or fair hadith.
However, "hasam" is not a recognised classification of Hadith.
It appears to be a misspelling of hasan.
Therefore, it is the option that does not belong among the classifications.
Answer:D. hasam
