Yeah I think general summaries are ok as long as they are actual summaries of multiple authors arent just mere repetitions of the authors statement and dont elongate the paragraph more unnecessarily Also Ill like to point out these mistakes in your comment  per Eliade approximative understanding partly of apparently nonArabian rites so not much Eildae never says it was nonArabian Shes talking about Monophysite rites and Monophysite was the largest branch of Christianity in Arabia    per Watt details that may be surmised by close analysis Muhammads life He also argues that these verses might be attacking Christian heresies rather than orthodox beliefs   Also in the final Ill like to say again the subject of the article isnt about Quran and its historicity and interpretations So adding more and more unnecessary arguments and interpretations makes the paragraph stray too far from the topic and unnecessarily elongates the paragraph with needless irrelevant text
