Wahb ibn Munabbih
"Wahb ibn Munabbih has related that the people of Quraish said to Allah's' Messenger: 'If you like we would enter your faith for a year and you would enter our faith for a year.'" (Abd bin Humaid, Ibn Abi Hatim). "...In this way, if what you have brought us is better than what we have, we would partake of it and take our share of goodness from it; and if what we have is better than what you have brought, you would partake of it and take your share of goodness from it."
