Science of Hadith (Al Bayquniyyah)
The knowledge of usul al-hadith is a science that serves the radiant Prophetic traditions; with it one can distinguish the Prophetic narrations in terms of authenticity and fabrication, soundness and weakness.
Al-Imam Abdullah ibn al-Mubarak said, The quality of the hadith is not in the conciseness of the isnad, rather its quality lies in the soundness of its narrators.
