Concept:The first revelation of the Qur'an was received by the Prophet Muhammad (peace be upon him) in a specific cave, not on the mountain or in the city itself.
The cave is known as Cave Hirah, located on a mountain near Makkah.
Explanation:The Prophet Muhammad (peace be upon him) often withdrew from society to worship and reflect in solitude.
He used to go to a cave on Mount Hira for meditation and devotion.
This cave, called Cave Hirah or Ghar Hira, is situated on Jabal Nur, which means "Mountain of Light."
During the last ten days of Ramadan, while he was in Cave Hirah, the angel Jibril appeared to him.
Jibril delivered the first verses of the Qur'an on the command of Allah.
At that time, the Prophet was about forty years old.
Jabal Nur is the name of the mountain where the cave is found, not the exact place of revelation.
Makkah is the whole city and does not point to the precise location.
Cave Thawr is connected to the Hijrah, when the Prophet hid from his pursuers, so it is incorrect here.
Therefore, the starting place of the Qur'anic revelation is the Cave Hirah.
Answer:C. Cave Hirah
