He simply picked up a hodge-podge of ideas that circulated over the trade routes and inserted them into his Quran (like the absurd non-death of Christ on the cross in Sura 4:157), claiming divine revelation from Allah. Hence, in clear and obvious ways he is not a reformer of Christianity (and Judaism), but a deformer of the two earlier religions.
Alichokifanya ni kwamba alichukua mchanganyiko wa mawazo yaliyokuwa yameenea kwenye njia za biashara na akayaingiza kwenye Kurani yake (kama wazo lisilo na mantiki lenye kukana kifo cha Kristo msalabani kwenye Sura 4:157), na kudai kuwa ni ufunuo wa kiungu toka kwa Allah. Hivyo basi, kwa njia ziliyowazi na dhahiri Muhammad hakuwa anauboresha ukristo (na Uyahudi), lakini alikuwa anaziharibu dini hizo mbili zilizo mtangulia.
