‘Al-Aql’ in Arabic known as the Intellect is a tool to understanding the realities of things. It is the only distinction between man and other living organisms, and the one who possesses it is referred to as ‘the intelligent one’. When the intellect is visualised in the brain, it symbolises thought and reflection; and when it is connected to the heart, it represents aspirations and desires. The statement, “the heart is the abode of guidance while the brain is the abode of thought” may be accurate. The intellect, which may be found in the heart or brain, is a spiritual substance made by Allah SWT and is attached to the human body; it is not like any physically imaginable body component or organ. It is one of the greatest blessings since it gives one the capacity to assess their surroundings and to understand what they must do and what they must avoid.

To achieve intelligence in relation to Tehzeeb e Ikhlaq, the intellect must be related well with moralities. This is because one’s ethics and moralities could be a direct illustration representation of one’s intellect. It is through the intellect that one realises one’s self-existence and one’s Lord, and to build and maintain a pleasant relationship with those around one, living or non-living organisms. As Allah says in the Quran, “Indeed, in all of this there are sure signs ‘of One Creator’ for people who would use their intellect to understand;” “Thus do We make distinct the signs for a people who would use their intellect to understand”.

When intelligence is in excess it can lead to being deceptive, fraudulent and being an imposture. Having lack of intelligence can lead to stupidity and ignorance. This therefore suggests that intellect that is void of morality is like a barren tree, and that with morality is like a fruitful tree.
