Praise be to Allaah.
We put this question to Shaykh Muhammad ibn Saalih al-‘Uthaymeen,
may Allaah preserve him, who answered as follows:
What they get (i.e., payments) without asking for it will
not detract from their reward.
Question:
The people who made this web-site say in one part of their site that
anyone who wants to place an advertisement with us on a monthly basis
has to pay a certain amount, in return for which they will place the
advertisements.
Answer:
If that is the case, then this money will detract from their reward,
because they are the ones who are asking for it. But if they take what
is given to them to help them with what they are doing, there is nothing
wrong with them taking it. It says in the hadeeth of ‘Umar that the
Prophet (peace and blessings of
Allaah be upon him) said: “If any of this money comes to you without
your hoping for it or asking for it, then take it, and whatever does
not come to you, do not trouble yourself about it (i.e., if it does
not come to you, do not seek it, leave it alone).”
(Narrated by al-Bukhaari, 1473)
And Allaah knows best.
