Are na-mehram bra sellers 'death' too?

Re: Are na-mehram bra sellers ‘death’ too?

Uqba b. Amir reported Rasulullah (sallallaahu alayhi wa sallam) stated: Beware of getting into the houses and meeting women (in seclusion). A person from the Ansar inquired: (Oh) Rasulullah (sallallaahu alayhi wa sallam), what about husband’s brother, (what can you inform me regarding him, what should our relationship be like towards each other,) whereupon Rasulullah (sallallaahu alayhi wa sallam) said: The husband’s brother is like death. (Book 26, Number 5400, Imaam Muslim.)

Another of similar hadith which was potentially ridiculed by OP.
