How should one act regarding the sudden feeling of hatred towards a righteous companion, after she had been a reason for drawing closer to Allah and performing acts of worship, and what are the consequences of this aversion for the girl and her companions?

What you feel towards your sisters is due to Satan, who seeks to sow discord among Muslims and make them detest good companionship. The Prophet, peace and blessings be upon him, said: "Indeed, Satan has despaired of being worshipped by the worshippers in the Arabian Peninsula, but he will sow discord among them." Satan seeks your isolation and makes it appealing to you. The Messenger of Allah, peace and blessings be upon him, said: "There are no three people in a village or in the desert among whom prayer is not established, but Satan has overpowered them. So, adhere to the community, for the wolf devours the stray sheep." You must return to your good companionship, be diligent in acts of obedience, and frequently supplicate to Allah to keep you firm in His religion, and mend the relationship by responding to their messages. Beware of isolation, for mingling is sometimes obligatory and sometimes desirable if it involves cooperation in righteousness and piety. Malice and envy are afflictions that harm the heart, and Allah has favored some people over others for a wisdom. You should hasten to do good deeds and abandon evil acts.
