Hazrat Moulana Ashraf Ali Thaanwi (rahimahullah) once mentioned the following:

Allah Ta‘ala created man as the most superior of all His creation, only due to the bounty of reasoning and intelligence which Allah Ta‘ala granted him. Therefore, a person should use his reasoning ability and intelligence in the correct way, and he should ensure that his reasoning and intelligence always remains subject to wahi (divine revelation – i.e. he should not employ his reasoning against the divine command of Allah Ta‘ala).

If a person’s reasoning does not conform to wahi (divine revelation), but goes against it, then such reasoning is not considered, and it is on account of such reasoning that we find people, night and day, falling into problems in simple and clear matters (i.e. on account of them leaving the divine command of Allah Ta‘ala which leads one towards complete guidance, they fall into problems and difficulties).

(Malfoozaat Hakeemul Ummat 11/187)
