English Commentary:
Supāri (Glans)
The term "supāri" (glans) refers to that part of the private organ which is covered before circumcision, and which becomes exposed after circumcision.
The meaning of "the circumcised parts meeting" is the same as that of the glans (supāri) becoming concealed within the woman's private part.
This narration is synonymous in meaning with the preceding narration; therefore, some have declared it to be authentic (sahih).
