Mursal Khafee (Hidden Generalization)Technically means that someone narrates something he did not hear fromsomeone whom he met or who was his contemporary using terminology implyingthat he heard it from him. The difference between Mursal Khafiy and Tadlees as-Sanad is that in the case of Mursal, he narrates from someone whom he did notstudy under whereas in Tadlees he narrates from his teacher. E.g.حدث َنا محمد بن الصباحِ‏ أ َنبأ َنا عبد ال ْعزِيزِ‏ بن محمدٍ‏ عن صالِحِ‏ بنِ‏ محمدِ‏ بنِ‏ زائِدة َ عن عمر بنِ‏عبدِ‏ ال ْعزِيزِ‏ عن عق ْبة َ بنِ‏ عامِرٍ‏ ال ْجهنِي ق َال َ ق َال َ رسول ُ الل َّهِ‏ صل َّى الل َّه عل َيهِ‏ وسل َّم رحِم الل َّه حارِسال ْحرسِ‏Muhammad ibn as-Sabbaah informed us [saying:] ‘Abdul-‘Azeez ibn Muhammadinformed us from Saalih ibn Muhammad ibn Zaa’id from ‘Umar ibn ‘Abdul-‘Azeez from ‘Uqbah ibn ‘Aamir al-Juhanee who quoted the Messenger of Allaah(r) as saying, “May Allaah’s mercy be on the watch guard who watched over theother watch guards.” 48‘Umar did not meet ‘Uqbah though he lived in his time according to al-Mizzee inhis book al-Atraaf.The Methods of RecognitionThis type of Irsaal may be identified by any one of the following three factors:(1) The statement of one of the scholars that such and such a narrator never metthe narrator from whom he was narrating or that he never heard anything fromhim.(2) The narrator informing on himself by admitting that he never met or hearddirectly from the narrator from whom he narrated.(3) If the hadeeth comes along another chain in which people are added between anarrator and the one from whom he was supposed to be narrating.48 Sunan Ibn Majah , Kitaab Jihaad Baab: Fadl al Haras wa takbeeer
