Our Lord, give us in this world [that which is] good and in the Hereafter [that which is] good and protect us from the punishment of the Fire.[2:201]
it is incumbent upon us muslims to strive for the betterment of this world as well as the aakhirah. we as muslims must always try avoid anything that goes against quran and authentic sunnah. we must not entertain anything that would displease our Rabb.
pornography is haram in islam and there is no doubt about it. your company is involved in it and now you know it. its rational that as human beings we first go through a phase called justification when defending something we want or when trying to avoid something which you may believe is not good for you. its the reason why you have said "I already ask the co. that I am not going to support any HARAM work in any manner either directly or indirectly. and they are agree with term and condition. Hope I am clear". you must understand that sometimes there is a very fine line between halal and haram. you may think that you are doing the right thing just because it is something you are afraid to let go.
....But perhaps you hate a thing and it is good for you; and perhaps you love a thing and it is bad for you. And Allah Knows, while you know not.[2:216]
you may still think that you are just an insignificant individual working in a different department in this company that supports pornography (we don't know to which extent or what other haram acts/businesses they might be involved in), so it wont affect me. Allah the mighty and sublime has warned us against this,
And cooperate in righteousness and piety, but do not cooperate in sin and aggression. And fear Allah ; indeed, Allah is severe in penalty.[5:2]
knowing and not doing anything to avoid it when you can is supporting/helping that cause. beware of the following hadith of wine, as it clearly explains the context of your question, insha Allah.
It was narrated from Ibn ‘Umar that the Messenger of Allah (ﷺ) said:
“Wine is cursed from ten angles: The wine itself, the one who squeezes (the grapes etc), the one for whom it is squeezed, the one who sells it, the one who buys it, the one who carries it, the one to whom it is carried, the one who consumes its price, the one who drinks it and the one who pours it.”
Grade :Hasan (Darussalam)
Reference : Sunan Ibn Majah 3380
wine itself is haram and can you see how the 9 people are involved in the process.so ask yourself who are you here?....knowing something is haram and entertaining it, when you have choice and means to avoid it is not acceptable.
Abu Sa'eed Al-Khudri may Allaah be pleased with him said: “I heard the Prophet sallallaahu `alayhi wa sallam ( may Allaah exalt his mention ) saying: "Whoever amongst you sees an evil, he should change it with his hand (i.e. physically), if he is unable, then he should change it with his tongue (i.e. verbally) and if he is unable, then he should change it with his heart (by detesting it in his heart) and that is the weakest level of faith." [Muslim]
Halal rizq is a very critical matter. Halal rizq Isn't just a halal income, Halal food or Halal sustenance, it's so much more than that. It has an effect on one's spiritual state as well as one's acts of Ibadah. Consuming haram rizq can affect one's Deen and one may not even realize it.
may Allah the mighty and sublime grant you mercy and guide you to the straight path.
Allah knows best.
