Imam Abdullah al-Haddad said:
“Brotherhood [and Sisterhood] for Allah’s sake is like a tree. It is irrigated with the water of mutual visiting and the fruit it bears is working together for the sake of goodness and taqwa. If it is not watered it will wither and if it does not bear any fruit it will be cut down.“
Imam al-Ghazali said in “The Revival of Religious Sciences” in the beginning of the section on Fellowship, Brotherhood, and Sisterhood:
“Know that fellowship is the fruit of good character and separation is the fruit of bad character. Good character necessitates mutual love, camaraderie, and getting along. Bad character brings about hatred, envy, and treachery.”
The Proof of Islam starts this section with this simple, yet profound quote. A quote that gives the recipe for bringing people together and building community: have good character and treat one another properly. That’s the starting point.
