Is sin incurred by one who does not speak to her quarreling colleague and does not seek reconciliation, and does the Hadith of the Messenger of Allah, peace and blessings be upon him, concerning those who quarrel and whose deeds are not raised until they reconcile, apply to her?

One must avoid excessive conversation with non-mahram women unless there is a need, and it should be limited to greeting them with a lowered gaze if temptation is safe. It is permissible for men to greet women and for women to greet men when temptation is safe.

Care should be taken to ensure the soundness of hearts and the absence of grudges among Muslims, striving to reconcile those who differ. Boycotting Muslims and turning away from reconciliation is prohibited, as the Prophet, peace and blessings be upon him, said: "Do not envy one another, do not turn away from one another, and do not boycott one another." And, "It is not permissible for a Muslim to abandon his brother for more than three nights; they meet, and this one turns away, and that one turns away. The best of them is the one who initiates the greeting."

However, if mixing brings harm to one's religion or worldly affairs, then boycotting is permissible at that time. There is a fear for anyone who boycotts his Muslim brother due to enmity and mutual hatred that forgiveness may be withheld from him on Mondays and Thursdays, as no one is forgiven except for a person between whom and his brother there is animosity until they reconcile.

The prohibited abandonment is to cease speaking to one's brother while meeting, turning away, and not greeting. Most scholars believe that abandonment ceases merely by greeting and responding to it, while others believe that it is not absolved until the situation returns to what it was, or that abandonment is not interrupted by a greeting if ceasing to speak harms the other person.
