Concept:The question asks us to identify the hadith whose main topic is the lawful (halal) and the unlawful (haram) from the numbered options given.
Explanation:The hadith that discusses the lawful and the unlawful is Hadith one in the set of hadiths under consideration.
In this hadith, the Prophet (SAW) said: "The lawful is clear, the unlawful is clear, and between them are doubtful matters."
Whoever avoids the doubtful matters protects his religion and his honour.
Whoever indulges in doubtful matters may soon fall into the unlawful.
The Prophet (SAW) gave the example of a shepherd who grazes his sheep near a private pasture and may eventually let them graze inside it.
He then said that every king has a private pasture, and the private pasture of Allah is what He has declared unlawful.
This hadith is reported by Al-Nu'man ibn Bashir and recorded by Bukhari and Muslim.
Therefore, the hadith that talks about the lawful and unlawful is number one.
Answer:D. one
