He treated the financial director and he gave him some money

If this
money belongs to the state, then it is essential to know under what category
a person could obtain it, such as if it comes under the heading of helping
the needy, rewarding higly-skilled persons, and so on. If you fit the
description, then it is permissible for you to take the money, otherwise you
should give it to those who fit the description. If you cannot do that, then
spend it as needed for your work, and do not take any of it for yourself. 

This
director should fulfil the trust with which he has been charged, and not
give this money to anyone except those who are entitled to it. 

If you can
advise him concerning that, then this is what you must do, because the
Prophet (peace and blessings of Allaah be upon him) said: “Help your
brother whether he is a wrongdoer or is wronged.” A man said: “O Messenger
of Allaah, I can help him if he is wronged but what if he is the wrongdoer,
how can I help him?” He said: “Stop him or prevent him from doing wrong.
That is how you help him.” Narrated by al-Bukhaari, 6952. 

If this
director is giving you this from his own money, then do not accept anything
from him, because that  comes under the heading of giving gifts to workers
that is forbidden in sharee’ah, because of the report narrated by
al-Bukhaari, 2597 and Muslim (1832) from Abu Humayd al-Saa’idi (may Allaah
be pleased with him), who said: The Prophet (peace and blessings of
Allaah be upon him) appointed a man from al-Azd to be in charge of
collecting the zakaah, and when he came, he said: “This is for you and this
was given to me as a gift.” He (the Prophet (peace and blessings of
Allaah be upon him)) said: “Why doesn’t he sit in the house of his father or
the house of his mother and see whether he is given anything or not? By the
One in Whose hand is my soul, none of you takes anything from it but he will
come carrying it on his neck on the Day of Resurrection, even if it is a
camel that is groaning or a cow that is mooing or a sheep that is bleating.”
Then he raised his hand until we could see the whiteness of his armpit and
said: “O Allaah, have I conveyed (the message)? O Allaah, have I conveyed
(the message)?” three times. 

According to
a version narrated by Muslim: Then he addressed us and praised and glorified
Allaah, then he said: “I appointed a man from among you to do this task
which Allaah has enjoined upon me, and he comes and says, ‘This is your
wealth and this is a gift that was given to me.’ Why doesn’t he sit in the
house of his father and mother so that gifts will be brought to him if he is telling the truth.” 

And Allaah knows best.
