Quranic Arabic Corpus
The Quranic Arabic Corpus is an annotated linguistic resource which shows the Arabic grammar, syntax and morphology for each word in the Holy Quran. The corpus provides three levels of analysis: morphological annotation, a syntactic treebank and a semantic ontology.
The goal of this website is to provide the first online, authentic, searchable, and multilingual (English/Arabic at the individual hadith level) database of collections of hadith by Prophet Muhammad (pbuh).
Islam Through the Eyes of Others
These books deal with the earliest references to Muslims and Islam in non-Islamic writings. Very interesting material to read.
