Is it permissible for a married Muslim woman to have a fraternal relationship in Allah with a Muslim man?

Cooperation in righteousness and piety is a divine command, but it must be subject to Sharia (definition) regulations, because believers are not infallible. Among these regulations: The basic rule regarding a Muslim woman meeting and conversing with a non-mahram (definition) man is prohibition, unless there is a need estimated according to its measure, and with adherence to Sharia limits such as avoiding khalwa (definition) (private seclusion) and looking at awrat (private parts). The woman must be polite in her speech and not speak in a soft, alluring tone, and she must adhere to the Sharia hijab (definition). This relationship is permissible if temptation (fitna) is secured against; otherwise, it is forbidden.
