How can a student balance obeying her mother, who refuses the formation of friendships, with her desire to continue a blessed friendship with a righteous girl who helps her avoid sins?

The Sharia emphasizes the importance of good companionship and its role in remaining steadfast in truth and righteousness, citing verses and hadiths that show that "a believer to another believer is like a solid structure," and that isolation is a danger that exposes one to the dominance of Satan. It also states that sitting with righteous people elevates one's spirit, unlike a bad companion. Righteousness towards parents and obedience to them are among the greatest acts of proximity [to Allah], but their obedience is not absolute. It is not permissible in an act of disobedience [to Allah], nor is it obligatory in matters that offer them no benefit or cause harm to the children, especially if the matter conflicts with an emphasized Sharia ruling. Likewise, their obedience is not obligatory in preventing a child from seeking what benefits him in terms of religion or worldly life. Therefore, obedience to the mother in staying away from good companionship is not obligatory, and the matter can be dealt with through gentle persuasion, or by concealing the matter from her if necessary, or by trying to introduce the mother to the girl to dispel her fears.
