Da'wah (Islamic call/invitation) based on knowledge

قُلْ هَـٰذِهِۦ سَبِيلِىٓ أَدْعُوٓا۟ إِلَى ٱللَّهِ ۚ عَلَىٰ بَصِيرَةٍ أَنَا۠ وَمَنِ ٱتَّبَعَنِى ۖ وَسُبْحَـٰنَ ٱللَّهِ وَمَآ أَنَا۠ مِنَ ٱلْمُشْرِكِينَ

Say, "This is my way; I invite to Allāh with insight, I and those who follow me. And exalted is Allāh; and I am not of those who associate others with Him."
