Imam al-Ghazali is one of the greatest reformers Islam has produced. His multifaceted service for Din has been acclaimed by the academia through centuries. One of his masterpieces is the Ihya Ulum al-Din (the regeneration of sciences). ‘Ulama say that, should all the books on different disciplines be burnt out, this book is sufficient to recreate them. One of the most appealing topics of this book is the chapter on Knowledge, where the great Imam shed light as to what is knowledge.
He has divided knowledge into two parts:
Religious knowledge (Ilm al-‘Áliyah’ ), and secular (or instrumental) knowledge (Ilm al-Áliyah). The former is acquired from the Qur’an and Sunnah. It is the most dignified knowledge and it is without doubt. The second type of knowledge is needed to enhance the understanding of the former since it was a revelation. Imam al-Ghazali subdivided the secular subjects into three subcategories:
Beneficial knowledge: This encapsulates those sciences that will benefit society and helps it to progress, e.g. medical knowledge and mathematics. Accordingly, the acquisition of these sciences and disciplines is Fard al-Kifayyah, i.e. if nobody acquires it, then the entire Muslim community of a particular locality will be sinful.
Neutral Knowledge: This category encapsulates those disciplines that will not really enhance one’s beneficial knowledge but there is nothing wrong if they are studied, e.g. the history of England.
Harmful Knowledge: This category comprises of those disciplines which are harmful, such as black magic and gambling. It is therefore, haram to acquire such knowledge.

If the parents, and later the teachers, brought him up in righteousness he would live happily in this
