Dought & clear,- Ruling on making phone apps for some educational projects andselling them.

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 dealwith 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 ofmodern technology to do that is one of the bestand
greatest good deeds, if a person does itseeking 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 everythingthat angers Allah, may He be
exalted, via electronic means by using the highest levels of modern
technology that mankind has attained.
