Ruling on making phone apps for some educational projects and selling them
Question

                Is it permissible to make phone apps to sell Islamic information? For example, the iPhone mobile phone has a number of apps that are sold via the Apple company, such as the electronic Mushaf, Saheeh al-Bukhaari, Saheeh Muslim, and so on. I would like to make apps like these, that deal with the Qur’an and Prophet’s hadeeths, for the iPhone and iPad, and upload them to the App Store as unique apps.
Praise be to Allah.
    Striving to spread knowledge and the Qur’an is a great good 
    deed, and making use of modern technology to do that is one of the best and 
    greatest good deeds, if a person does it seeking to please Allah, especially 
    nowadays when followers of whims and desires and the people of kufr, 
    hypocrisy and division are hastening to spread evil, immorality, shirk and 
    kufr, and everything that angers Allah, may He be exalted, via electronic 
    means by using the highest levels of modern technology that mankind has 
    attained. 

    Making these Islamic apps that contain nothing that is 
    contrary to the teaching of Islam, rather they are aimed at spreading the 
    religion of Allah, and teaching Qur’an and hadeeth, is a great and blessed 
    good deed, if you do it sincerely for the sake of Allah and with the right 
    intention, whilst striving to do your work well and referring it to a 
    committee of specialists in the field in which you are making the app 
    (Qur’an, hadeeth, and so on), for them to check it from an academic point of 
    view and to make sure that it is free of errors. 

    There is also nothing wrong with you selling it to people via 
    this electronic seller (the App Store).
