"个别传闻"（khabar al-aahaad）指的是由一个数量未达到三个时代（圣门弟子时代、再传弟子时代、再再传弟子时代）中"穆塔瓦త尔"（tawaatur）程度的人所转述的圣训，并且不考虑其后时代的情况。它表示的是最大的可能性，而非确定性。判决依据它进行推导，正如依据"穆塔瓦特尔"圣训和"迈什胡尔"（mashhour）圣训进行推导一样。 对个别传闻的研究是乌苏勒（usool）问题中最重要的内容之一，因为鉴于"穆塔瓦特尔"圣训数量稀少，大多数教法判决都以它为基础。当个别传闻同时满足两个条件——传述的条件（riwaayah）和对其内容的理解（diraayah）——时，就必须将其作为行动的依据。 先知ﷺ曾派遣圣门弟子中的个别人前往各国，传播伊斯兰、讲授教法并传述圣训，例如他派遣穆阿兹（Muaadh）前往也门。如果穆斯林不必依据个别传闻行动，先知ﷺ便不会满足于仅派遣圣门弟子中的个人，而会派遣群体前去。

The individuals report is what was narrated by a number which does not reach the extent of the tawaator in the three eras (Al Sahaabah, Al Taabi'ine, and Taabi'y Al Taabi'ine), and no consideration to what came after them. It denotes the most probability, not the certainty. The verdicts base on it in their derivation as they base on the mutawaatir Hadeeth and on the mashhour Hadeeth. The research of khabar Al Aahaad is from among the most important usoul issues, because it is the basis of most of the verdicts for the fewness of the mutawaatir Sunnah. Khabar Al Aahaad must be taken as basis for the actions when it fulfills both: the conditions of the transmission (riwayah) and the knowledge of its content (dirayah). The Messenger (SAW) used to send individuals from the sahabah to the countries to call to Islam, teach the verdicts, and narrated the ahaadeeth, the way He sent Muazth to Yemen. So had it not been a must for the Muslims to act according to khabar Al Aahaad; the Messenger (SAW) would not be satisfied by sending individuals from among the Sahabah, but he would then send groups.
