Sheikh Al-Ansari started his book Al-Makasib with the forbidden gains section, which is the first section of the book Al-Makasib. This part appears to the observer that what is meant by profits is shops or what is bought and sold, but what the Sheikh wrote is completely different from this understanding. Rather, the intention of Sheikh Al-Ansari by forbidden profits is everything that a person earns from work, deed, or saying by hand, by tongue, or through himself, the ruler, such as fornication. Backbiting, lying, witchcraft and sorcery, and if this gain is without money or has no benefit, then it is earning bad deeds and disobedience, and man will be rewarded for it on the Day of Resurrection.
