Article 119: It is prohibited for any man or woman to undertake any work which could undermine the morals, or causes corruption in the society.
The evidence for this article is what was narrated from Rafi’ b. Rifa’ah who said
«وَنَهَانَا عَنْ كَسْبِ الأَمَةِ إِلاَّ مَا عَمِلَتْ بِيَدِهَا وَقَالَ هَكَذَا بِأَصَابِعِهِ نَحْوَ الْخَـبْزِ وَالْغَزْلِ وَالنَّـفْشِ»
“The Prophet forbade us from benefiting from the slave woman except that which she did with her hands, and said ‘in this manner’ with his fingers, such as bread-making, sewing, and inscribing” reported by Ahmad and authenticated by Al-Zayn, as well as Al-Hakim who also authenticate it; in other words, he prohibited the woman from any work which took advantage of her femininity, while allowing any other type of work. This is understood from the part of the narration which mentions “except that which she did with her hands”, in other words, intended to benefit from her efforts, and its understanding is the prohibition of taking advantage of her femininity. Also, the Shari’ah principle “The means to something forbidden is also forbidden” prohibits any work that could lead to anything forbidden. And the Shari’ah principle “If one type of a permitted thing leads to harm, only that one is prohibited, and the thing remains permitted” prohibits every person, male or female, from working in a job originally permitted for men and women, if the work for that person specifically would lead to a Haram for him, or the Ummah, or the society, whatever type of Haram that may be.
