Is it permissible for my wife to visit women who do not offer Salah (Prayer),
bearing in mind that their husbands also do not pray and may intermix with female visitors?
(Part No. 12; Page No. 376
If there is any benefit to be realized from your wife visiting these ladies, such as calling them to the Way of Allah (Exalted be He) and advising them to carry out the obligations of Islam, and there is no Munkar (that which is unacceptable or disapproved of by Islamic law and Muslims of sound intellect) involved, like intermixing with men, it is permissible for her to visit them. Otherwise, it is not permissible.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
