What is hadith fabrication?

Answer 1

Fabrication of a hadith means a false hadith which is truly unauthentic and was not said by the Holy Prophet PBUH. The enemies of Islam, in the early phase of Islamic history, decided to damage the authenticity of the treasure of the prophetic knowledge, if not destroy it altogether. Their efforts, however, were thwarted by the efforts of imāms of the science of Hadīth criticism. They exerted their full efforts in sifting the true knowledge from false fabrications. They pointed out the loopholes through which the weak Aḥādīth were mixed with the sound ones. The intensity of fabrications can be imagined by considering the fact that only a few thousand narratives could pass the test of a set criterion for the sound Aḥādīth from hundreds of thousands of traditions.
