Is it permissible to mix freely with my brothers-in-law, my sisters' husbands, and my cousins?

The questioner: He says: Is it permissible to mix with my husband's brothers -The questioner : isa woman - and the husbands of my sisters and my maternal uncle's sons, or is it not permissible? And sitting with them and talking?

The Shaykh : Is this also a question from a woman?

The questioner : It is a woman.

The Shaykh : The mahram are the only ones with whom a woman is permitted to mix, sit, and converse. As for relatives who are not mahram, it is not permissible for a Muslim woman to mix with them or speak to them; because this is among the means and causes that open the door to evil, as was explained in a previous answer to another issue. And the Prophet (peace and blessings be upon him) indicated the danger of such mixing when he forbade being alone with a woman. It was said to him (peace be upon him): "What do you say about the close relatives?" He said: .
That is, it was said to him: "What do you say about the relatives of the husband or wife if a woman is alone with them?" These are relatives—meaning, as they say today, unfortunately, if such mixing or seclusion is not condemned, the woman says: "My brother, there is no stranger here; he is my cousin, my maternal cousin, or my aunt's son, and so on." So the Messenger (peace be upon him) refutes this claim and says: ; meaning: a woman's mixing with her non-mahram relatives exposes herself to death, a spiritual death.
