Will he who establishes a website containing the Quran, Islamic and ordinary programs, and Islamic anthems be rewarded, and will he be sinful if someone uses an ordinary program for a sinful act?

We hope you receive abundant reward and goodness for recording the Holy Quran and beneficial programs on your website, as this benefits people, spreads knowledge, and guides towards good. There is no sin upon you if someone downloads a program and uses it in a way that displeases Allah, as long as you were unable to prevent them from doing so, for Allah Almighty says: "And no bearer of burdens will bear the burden of another."
