Praise be to Allaah.
You say that you are in charge of accounts, preparing and
equipping, and that buying the apartment came under the heading of
equipping. Based on that, the work that you did is part of the work for
which you are paid a salary, so you do not have the right to take anything
from either the buyer or the broker, because this comes under the heading
of what is called “gifts to workers”, which is haraam wealth.
The Prophet (blessings and peace of Allah be upon him)
appointed a man in charge of collecting zakaah. When he came he said: This
is for you, and this was given to me. The Messenger of Allaah (blessings and
peace of Allah be upon him) stood up on the minbar and praised and glorified
Allaah, and said: “What is the matter with a worker whom I send, and he
comes and says, ‘This is for you and this was given to me’? Why doesn’t he
sit in the house of his father or the house of his mother and see if he is
given anything or not?”
Narrated by al-Bukhaari (7174) and Muslim (1832).
Al-Nawawi (may Allah have mercy on him) said: In this hadeeth
we see that gifts to workers are haraam, because it is a betrayal of his
position and what has been entrusted to him. In the same hadeeth, the
Prophet (blessings and peace of Allaah be upon him) explained the reason why
gifts to workers are haraam: it is because the worker is only given that
gift because of his position. So it is not like a gift to someone other than
the worker, because such gifts are mustahabb. The ruling on that which is
taken by a worker and the like in the name of it being a gift is that it
should be returned to the giver, and if he refuses (to take it back) it
should be added to the bayt al-maal. End quote.
Based on this, if you took something from the buyer or
broker, you have to give it back to him.
