Concept:Monotheism means believing in the oneness of Allah, and Surah al-Ikhlas is the Qur’anic chapter devoted entirely to this theme.
Explanation:Surah al-Ikhlas is known as the chapter of pure sincerity.
It teaches that Allah is One and has no partner.
It states that Allah is Eternal and independent of all things.
It also states that Allah has no offspring and no equal.
Thus, it gives the clearest and strongest declaration of monotheism in the Qur’an.
Al-Kafirun rejects the worship of false deities, but al-Ikhlas directly affirms the oneness of Allah.
Al-Qadr is about the Night of Power, while al-Naar is not connected to this theme.
Therefore, the surah that emphasizes monotheism most clearly is al-Ikhlas.
Answer:Option B — al-Ikhlas.
