A Muslim businessman has asked a Muslim female customer for a sexual favour in lieu of some business information.

Answer

What is so surprising in the request of the faasiq/faajir businessman? This is the norm in this rotten society. The woman herself is lewd having prostitute tendencies, hence the audacity of the faajir. If she was not a faasiqah / faajirah herself, she would not have found herself in the zina situation with the shaitaan. Norms of this kind are the logical consequences of rebellion against Allah Ta'ala. When Allah's Law of Hijaab is abandoned and even scorned and mocked, then it is illogical and stupid to express annoyance at shaitaani advances of the kind mentioned in the question.
