Resources in English
The main resource in English used by WikiIslam is QuranX: quranx.com
QuranX contains English translations of all of the major orthodox Sunni hadith and tafsir collections as well as multiple translations of the Qur'an along with the original Arabic. WikiIslam templates utilize QuranX for the Qur'an and Hadith quotes. These templates will automatically link to the specified Quran or Hadith passage on QuranX. Please see WikiIslam:Citing, Linking, and Quoting and WikiIslam:How to Edit for more info on how to use these templates.
