Concept:This question tests your knowledge of the events surrounding the first revelation received by the Prophet Muhammad (SAW).
It specifically asks you to identify the person who spoke these words of affirmation and warning.
Explanation:When the Prophet Muhammad (SAW) received the first revelation in the Cave of Hira, he was deeply shaken and returned to his wife, Khadijah.
To comfort and guide him, Khadijah took him to her learned cousin, Waraqah b. Nawfal.
Waraqah was a devout Christian scholar who was familiar with the earlier scriptures.
After listening to the Prophet's account, Waraqah confirmed that the angel who visited him was the same angel (Jibril) who had brought revelation to Prophet Musa (AS).
He then declared, "By Him who dominates my soul, I swear that you're the Prophet of this nation."
Waraqah went further to warn the Prophet that his people would abuse and persecute him once he began preaching the truth openly.
He firmly promised that if he lived to see that day, he would surely assist the cause of Allah.
Therefore, the speaker in the statement is Waraqah b. Nawfal, and not any of the other personalities mentioned in the options.
Answer:B. Waraqah b. Nawfal.
