The Path of Moderation in Islam...
Since purifying the soul has this level of importance, it is obligatory
upon each Muslim who desires good for himself to give great importance
to this matter and to struggle against his soul in his life to actualize
this praiseworthy goal; in order that he may be successful in his
worldly life and his hereafter, and so that he may enjoy true happiness.
The soul has a right upon the Muslim, as the messenger of Allah (صلى
الله عليه وسلم) has said:
وان لنفسك عليك حقاً
“Indeed, your soul has a right upon you.”
He has erred who believes that the right of the soul is that one is
harsh upon it and deprives it of its rights that Allah has created is
with an innate need for. Likewise, he has erred who believes that the
right of the soul is that one is negligent and neglectful of its
management and leaves it drowning in its lusts, and the likes.
Purification of the soul is totally different from the likes of this.
Rather, purification of the soul is by way of the legislative methods,
balance, and moderation, such that there is neither negligence nor
exaggeration. Instead, it is by clinging to the guidance of the prophet
(صلى الله عليه وسلم) and his firm methodology.
I will mention, within this concise work, ten importance principles
which will assist the Muslim in purifying and strengthening his soul as
well as cleansing it from everything which would sully and defile it.
