An _hadis hasen_, “an elegant tradition,” is one, the authority of which goes back, like that of the _hadis sahih_, to the _mâsúm_; but, according to the narrative of a venerable Imám, in this way, that although, in regard to the narrator of it, the words _sikah âdíl_, “trusty and just,” have not come down to us from the historians, yet they have praised him in other words. An _hadis músik_, “a strong tradition,” is that, in the description of whose narrators the words _sikah âdil_ have been used by the historians, but some or all of the narrators of which are not _Imámís_, “followers of Ali.” An _hadis sâíf_, “a weak tradition,” is that in which none of these three conditions are found; viz.: 1st, the inference from the commendation of _sikah âdil_; 2nd, a praise other than these two words; and 3rd, the qualification _sikah âdil_, with erroneous belief on the part of the narrator. A tradition is either _in regular succession_, or _not in regular succession_. A tradition is in regular succession, when a great multitude on the authority of a great multitude make the same narration, until it reaches to the _mâsúm_, in such a manner, that the number of each multitude, in each particular age, shall have been so great as to exclude the idea of their having combined in telling a lie. A tradition is without a regular succession, when the number of narrators does not, in all or several stages, reach to that multitude, as before said, and this kind of tradition is called, in the peculiar idiom of the masters of history, _the information of one_. Among the Akhbarians, there is no such arrangement and classification of evidence, and God knows the truth. The author of this book writes what he has learned of the religion of the _Akhbáríns_ from the Amíns of this doctrine, one of whom was Muhammed Razái Kazvíní. They call themselves _Akhbárín_, “dogmatic Traditionists,” because they place the centre of their belief in the prophetic book,[581] and employ no reasoning. _Mulla Muhammed Amín_, after having acquired the requisite theoretical and practical knowledge and that of the law, went to Mecca and to the revered places, and he declared openly, that controversial dialectics belong not to the rule of the ancient Shiâhs. The author of this book writes what he has heard from pious persons, the confidents of secrets of this sect; whoever desires to know more of it, may have recourse to the book _Faváid Almadíniy_, which is the composition of the last mentioned writer. The following passage is said to be found in the sacred writings: “God take compassion on the man of whom I know whence he comes, where he is, and whither he goes.”
