What is the correct way of going out in the cause of Allaah calling to Islam, according to the Sunnah of the Prophet, sallallaahu ‘alayhi wa sallam?

All perfect praise be to Allaah, The Lord of the worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and messenger.

 Going out in the cause of Allaah The Almighty for Da‘wah, and guiding people to the right path does not have one specific method, because it is a means of delivering the message of Allaah The Almighty. Therefore, the one calling others to Allaah can meet people in mosques, market places, the places where they gather, visit them in their homes, or set up educational centers in their area and so on.

Allaah Knows best.
