"Verily, We have sent it down as an Arabic Qur'an in order that you may understand" (Surah Yusuf, verse 2)

Among the blessings of Allah, Intelligence is a highly valuable one but ignored by humans. Intelligence distinguishes man from the rest of the creations in this universe. ‘Aaqil’ is an honourable term to define human beings.

And if you should count the favor of Allah , you could not enumerate them. Indeed, mankind is [generally] most unjust and ungrateful ( Surah Ibrahim, 34)

Man is bestowed with leadership through a blessed Intelligence

Indeed, we offered the Trust to the heavens and the earth and the mountains, and they declined to bear it and feared it; but man [undertook to] bear it. Indeed, he was unjust and ignorant (Surah al-Ahzab verse 72)

Man picked up the trust because of his intelligence. Therefore if someone does not use his intelligence then he is said to be an animal.

Intelligence is a blessing and it will be asked how we used it

Indeed, the hearing, the sight and the heart - about all those [one] will be questioned ( Surah Isra, verse 36)

Using intelligence has been made obligatory by Allah and nobody is allowed to ignore it. The command to use our intelligence is repeated around 95-100 times in the Qur’an. For example:

Afala ta’qiloon? Will you not use intelligence?

Afala yatadabbaroon? Will you not ponder?

Using intelligence is highly appreciated by the Qur’an, "And the worldly life is not but amusement and diversion; but the home of the Hereafter is best for those who fear Allah , so will you not reason?" (Al-An’am, verse 32)

It is a part of intelligence to overlook the materialistic delight of the world and be focused on the life hereafter. The former is temporary and the later is long lasting.
