Means of Da'wah: Are They Prescribed or Based on Ijtihad?

Question:
He says: May Allah protect you, are the means of da'wah (calling others to Islam) based on specific religious texts or based on independent legal reasoning?

Answer:
The means of da'wah, the means, are they based on specific religious texts? The methodology of da'wah, the methods of da'wah, and the styles of da'wah are based on specific religious texts, according to what came from the Messenger (peace and blessings be upon him), with clear guidance, "I and those who follow me" . So they are based on specific religious texts. As for the means, you find them in every age according to its circumstances. For example, radio, the microphone in front of me now; this did not exist in the beginning. The means that have emerged, such as riding in cars and traveling in them for da'wah, did not exist in the beginning. These are called means. There is no harm in these; they renew as times and eras renew. Yes.
