While His Wife Talks to the Man at the Store…
Shaikh Muḥammad ibn Ṣāliḥ Al-ʿUthaimīn, may Allāh have mercy on him, said:
As for what some women do of much talking to the men who work at shops and stalls, this is against what’s been legislated [in Islam], and there’s a tremendous likelihood of falling into evil [from this].
Similarly is what we witness of someone or another coming with his wife or womenfolk to tailors or their like, and then staying in his car [while] letting the woman go speak to the tailor or the man at the store, while he [himself isn’t able to] hear what’s going on between the two of them.
This, in reality, is from a lack of al-ghairah [possessiveness and protectiveness over one’s womenfolk] in this man; otherwise, how can he allow himself to stay in the car while the woman speaks to the man at the store, be he a tailor or other than that.
