12. Amīr al-mu’minīn, peace be upon him, said: The most helpless of all men is he who cannot find a few brothers during his life, but still more helpless is he who finds such a brother but loses him. 
 It is not difficult to attract others by good manners and cheerfulness and to befriend them by sweet speech because no physical exertion or mental worry is required for this: and after making friends it is still easier to maintain the friendship and good relations because for making friends some effort or other is needed while for maintaining it no difficulty is to be surmounted. Therefore, no one can be more wretched than the man who cannot even retain a thing which could be retained just by keeping away a frown from the face. The intention is that a man should meet everyone with good manners and cheerfulness so that people may like to associate with him and extend a hand of friendship towards him.
