The second source of Islamic Shariah is the Hadith or the sayings and deeds of the Prophet. But those who advocate executing the command to kill any abuser of the Prophet will not find a single line to support their argument. They might establish their stand if they could quote a tradition of the Prophet which clearly says, ‘Anyone who abuses your Prophet should be killed.’ But we can say with certainty that in the whole body of Hadith literature, no such authentic tradition has been recorded by anyone.
Imam Muhammad bin Ahmad Az Zahbi (d. 1348) wrote, ‘A Hadith which is not known to Ibn Taimiyya is not an authentic Hadith.’ But even Ibn Taimiyya, renowned as a great religious scholar, failed to present an authentic Hadith to this effect. In his book he quotes a tradition, the authenticity of which he is not quite certain. Its wording is as follows, ‘Anyone who abuses any of the prophets should be killed.’ Ibn Taimiyya himself wrote of this Hadith that it was possibly fabricated, and that only if its authenticity were proved, could it serve as an argument that abusers of the prophets should be killed.
Now even 700 years after the publication of Ibn Taimiyya’s book, no scholar has yet written about the source and authenticity of this tradition. In such a case it can be concluded with certainty that it is a fabricated Hadith. And a fabricated Hadith is worthless.
