What is the reason for the revelation of Surat An-Naml from verse 59 to 65, and what is its purpose?

There is no known specific reason for the revelation of the verses of Surat An-Naml in question. However, their objective is to affirm the Oneness of Lordship (Tawhid ar-Rububiyyah) and the Oneness of Divinity (Tawhid al-Uluhiyyah), and to clarify the interrelation between them. The verses begin by commanding Prophet Muhammad (peace be upon him) to praise Allah for destroying the disbelievers and for His peace upon the believers. Then, the verses showcase Allah's power in creation to challenge the polytheists and to prove that whoever acknowledges the Oneness of Lordship is obligated to acknowledge the Oneness of Divinity, and that separating them is a mistake.
