Is spreading the word of Islam a sunnah?

Question

Can we get sunnah from spreading the word about islam, or by guiding someone to Islam?

Answer 1

Giving Dawah is definitely the sunnah of the Prophet ﷺ, but its ruling is that it is Fard, i.e. Fard al-Kifayah.

ولتكن منكم أمة يدعون إلى الخير ويأمرون بالمعروف وينهون عن المنكر وأولئك هم المفلحون

And let there be [arising] from you a nation inviting to [all that is] good, enjoining what is right and forbidding what is wrong, and those will be the successful.

^{— Quran 3:104}

قل هذه سبيلي أدعو إلى الله على بصيرة أنا ومن اتبعني وسبحان الله وما أنا من المشركين

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

^{— Quran 12:108}
