HEART
- Allah has not given any man two hearts,
al-Ahzab
33:4
However, there are people who are borned with multiple hearts, admitted by anatomists like Geoffrey-Saint-Hilaire, Littre, Meckel, Colomb, Panum, Behr, Paullini, Rhodius, Winslow and Zacutus Lusitanus (G. M. Gould, W. L. Pyle, Julian Press, 1896, Anomalies and Curiosities of Medicine, cited by Lactantius, Embryology in the Quran). The Qur'an's statement appears to be in error.
