The hadiths (traditions) are supposedly reliable records of the doings and sayings of the prophet. They are fundamental to Muslim belief and practice.
If the hadiths are indeed reliable then the ‘prophet’ had some pretty whacky ideas. A few examples:
•A Muslim eats in seven intestines while a Muslim eats in one intestine (Sahih Muslim 3:15:862)
•People should avoid lifting their eyes towards the sky while supplicating in prayer, otherwise their eyes would be snatched away (Sahih Muslim 1:863:623)
•Allah’s apostle said, if a fly fall in the vessel of any of you, let him dip it into the vessel and then throw it away, for in one its wings there is a disease, and in the other wing healing (Sahih Bukhari 7:673)
•The prophet ordered them to go to the herd of camels and to drink their milk and urine (Sahih Bukhari 1:234)
If these hadiths can’t be trusted, why trust the rest?
