If the owner of an Islamic web-site takes payment for advertisements, will that detract from his reward?
Question

                We are a group of young men who are seeking reward with Allaah by putting an Islamic web-site on the Internet. The site has started to bring us some income through the advertisements placed on the site, etc. If we take this money and rely on it – after Allaah –to prepare for marriage, will this detract from our reward? We have read that Ibn Hajar said in Fath al-Baari that the one who takes a worldly reward for an action that has to do with the Hereafter, that will detract from his reward in the Hereafter.
Praise be to Allah.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.
