They say, "There are 600,000 hadiths." According to this statement, our Prophet (saas) should have said one hadith each hour starting from his birth. And these only cover the hadiths accepted, selected by Bukhari; and some say that Bukhari had chosen them among one million hadiths, others say he had chosen them among three million hadiths. Even if our Prophet (saas) had lived for a thousand years, he wouldn't have enough time to say all these hadiths. That means some of them are made-up, fake hadiths. Even a child would have understood this. - Harun Yahya
