None of the faculties endowed by Allah Almighty have been granted to man so that they may be wasted; rather, their discipline and proper use is the true means by which they are nourished and developed. This is why Islam has not taught that the faculties of virility be slaughtered completely or that the eye be gouged out. Instead, it teaches their proper use and the purification of one’s inner self. In this respect, Allah the Exalted states:
َقَدْ أَفْلَحَ الْمُؤْمِنُوْن
“Surely, success does come to the believers.”
Then, after illustrating the life of a righteous person, God Almighty draws a conclusion in the following words:
وَأُولٰٓئِکَ ھُمُ الْمُفْلِحُونَ
And it is they who shall prosper.
That is to say, those who tread the path of righteousness; those who believe in the unseen; those who establish or set upright their Prayer when it begins to fall as it were; those who give from that which is bestowed to them by God; those who, irrespective of their own thoughts and fancies, believe in all the divine scriptures sent by God, ultimately attain to the level of certainty. It is these very people who are truly guided and who tread a path that goes on to lead a person to success. Therefore, it is such people who are triumphant and who shall reach their final destination, and who have been delivered from the perils of the journey before them. Hence, from the very outset, Allah the Exalted has given us a teaching of righteousness and bestowed upon us a book, which also provides counsel on how to develop piety. And so, let my community grieve, more than anything else, over whether they possess righteousness or not.
