time for designation of mabī‘ (object of sale) in wholesale

in the islamic legal system, sale contract is regarded as among appropriative (tamlīkī) contracts, without any difference existing between the designation of the object of sale and its being wholesale (kullī). thus, there has been a considerable controversy among the jurists on the time for designation of mabī‘ (object of sale) with the presumption that mabī‘ is wholesale, which would bring about different and in some cases contradictory impacts. elucidation of this crucial issue and its analysis for achieving a definite theory can diminish diversity of views and make the rulings of this widely used contract more transparent. civil law is brief about this issue, which has caused some lawyers, following the western legal systems, to regard bay‘ as commitment (ahdī) with the presumption of mabī‘ to be wholesale and to exclude it from appropriative contracts. in this research, first an accurate elucidation of the concept “wholesale” and its different types is presented and thereby various opinions of the jurists have been examined in relation to the time for designation of wholesale mabī‘. based on the findings of this writing, the joint (mushā‘) wholesale is designated by partition (ifrāz) and in designated wholesale (kullī dar mu‘ayyan) and indebted wholesale (kullī dar dhimma) the seller’s serious intention, to whom the customer has entrusted the selection and surrender of the wholesale instance, would be the criteria for designation of mabī‘.
