How should a female da'iyah (preacher) act with her older, less knowledgeable colleague, when the attendees request that the da'iyah continue giving lectures, and how can she avoid the misunderstanding that she desires prominence?

It is advisable to continue inviting people to Allah and seeking knowledge, and to coordinate and consult with female callers to Islam. Explain the matter to the recipients as an arrangement for the benefit to become widespread. However, if the lecturing sisters speak without knowledge, they must be advised, and the other sisters should be advised not to attend their lectures.
