What is the benefit of the parables mentioned in the Noble Qur'an?

Al-Shinqiti said in his interpretation of the verse: "And We have certainly diversified in this Qur’an for the people from every [kind of] example; but man has ever been most quarrelsome," that Qur’anic parables are extremely profound in their lessons, admonitions, and deterrents. Only people of knowledge can comprehend their meanings. Part of their wisdom is to remind people and make them reflect. Allah has clarified that parables guide some people and lead others astray, as in His saying: "Indeed, Allah does not shy away from presenting an example – that of a mosquito or what is [even] above it. And as for those who have believed, they know that it is the truth from their Lord. But as for those who have disbelieved, they say, 'What did Allah intend by this as an example?' He misleads many thereby and guides many thereby. And He misleads none thereby except the defiantly disobedient." So, those who responded understood the parables and benefited from them, and these are the ones whom Allah guides. As for those who did not respond, they did not comprehend them, and these are the ones whom Allah leads astray and describes as defiantly disobedient.
