to Ja'far b. Muhammad al-'A imi, ?O 'A im, how are you at maintaining contact with each other and offering consolidation to each other?' [He said] I said, 'The best that anyone can be.' He said, 'Do any of you come to your brother's shop or his home in times of hardship and you pull out your purse for him to take whatever he needs without disapproving of him?!' He said, 'No.' Imam (AS) said, 'Then you are not at a state of mutual assistance that I love.'
