Among the various forms of the muʿallaq are the following:
• That the entire ⦗1⦘ isnad is dropped and one ⦗2⦘ simply states, for example, “The Messenger of Allah (peace and blessings be upon him) said….”
• That everything is omitted except the Companion; or that nothing remains except ⦗3⦘ the Successor together with ⦗4⦘ the Companion.
• That the compiler omits the person who related the report to him and attributes it to someone ⦗5⦘ higher in the chain. If that higher transmitter is one of the compiler’s own teachers, ⦗6⦘ the scholars have differed: is this to be called a taʿlīq or ⦗7⦘ not?
The sound view in ⦗8⦘ this matter is to differentiate: if, by explicit statement or by careful comparison, it is known that the compiler was guilty of tadlīs, the report is ruled accordingly; otherwise it is treated as a taʿlīq.
The muʿallaq has been placed ⦗9⦘ among the rejected ⦗10⦘ categories only because the status of the omitted narrator is unknown. Yet ⦗11⦘ it may be judged authentic once he becomes known—namely, when the same report appears with that narrator ⦗12⦘ named through another route.
