I was wondering, what are ways of spreading Islam (or proselytizing) according to Quran and Hadiths?
I am open to any school of thougths. I'm here not to argue, but rather I want to know the gamut of the teachings concerning proselytization in Islam.
Please cite the Quran and Hadiths (in English please), when you are answering.
NB: Note that, the question is different from, How do Muslims proselytize* in non-Muslim areas?, because that question is asking about cultural things and I'm asking about what Quran and Hadiths teach.
If anything is unclear, please comment before answering.
