Are there any copyright restrictions on reproducing English translations of the Quran?

I am planning to build a simple mobile app that provide the user with extracts from the Holy Koran, collection of the Ahadith and the Sunnah. I will be providing the Arabic text as well as the English translation and transliteration. Are there any copyright restrictions on reproducing these English translations & transliterations? I am intending to use the late Yusuf Ali's widely respected English translation of the Holy Koran. Regards the ahadith and Sunnah, I have not confirmed a source yet. I realised that a similar copyright question was asked here previously: https://islam.stackexchange.com/questions/24696/license-of-translation-software-quran-and-hadits I'm just hoping for a little more information.
