How can the call to Allah be directed in the absence of role models to avoid sufficiency with knowledge without action, and what is the importance of addressing political issues in the call to spare youth from decadence or extremism?

Righteous companionship and practical دعوت are more impactful than words. The preacher must act upon what he preaches. Modern media should be utilized for da'wah for those who cannot sit with scholars. The preacher should teach people matters of their religion with wisdom and gentleness, and clarify the truth to rulers and the general populace regarding their needs. The preacher should only invite to what he knows, and refer what he does not know to scholars known for their uprightness and sound creed.
