al-Mandhoomah al-Bayqooniyyah is a short poem on the sciences of hadeeth. It is an introductory text on Mustalah hadeeth and gives definitions and explanations of terms used by muhaditheen such as: saheeh, daeef, mawqoof etc.
The poem itself is very short and precise but it requires a sharh to take full benefit from it. A sharh is available by Shaykh Ibn Uthaymeen (rahimahullah). The next text a student would learn in the field of Mustalah al Hadeeth would be Ibn Hajr’s: Nukhabatul Fikr.
