All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah and that Muhammad is His slave and Messenger.
You will be rewarded, Allah willing, for giving out Islamic leaflets, because it is considered a good act. There is nothing wrong giving out a leaflet that contains views of a scholar that you believe to the preponderant opinion. If people were to refrain from publishing books because they contain what they do not believe to be the preponderant opinion, then there no book would have ever been published.
Allah Knows best.
