I said to Abu 'Abd Allah (a.s), 'What is the right of a believer on a fellow believer?' 'I feel sympathy for you,' he replied, 'I fear that you would know and not act upon it and you would neglect it and not safeguard it.' I said, 'There is no power and no strength except with Allah!' Believers have seven obligatory rights incumbent on each other,' Abu 'Abd Allah (a.s) said, 'each of these rights are mandatory on brothers-in-faith to fulfill. If he (a believer) omits any right from these, he has come out of the guardianship of Allah and has forsaken obedience to Him. The simplest of these rights is that you should love for him (your brother-in-faith) what you love for yourself and you should despise for him what you despise for yourself. The second is that you should help him with your self, your wealth, your tongue, your hands and your feet. The third is that you should pursue what pleases him and avoid his displeasure and obey his command. The fourth is that you should be his eyes, his guide and his mirror. The fifth is that you should not fill your stomach whilst he is hungry, you should not be quenched whilst he is thirsty and you should not clothe yourself whilst he is naked. The sixth is that if you should have a servant whilst he does not have one and you should have a maid to serve you and he does not have a maid to serve him; you should send over your servant to wash his clothes and prepare his food and bedding. The seventh is that you keep his vows, answer his calls, respond when he invites you, visit him when he is ill and accompany his bier; and if he should have a need, you should rush to fulfill it and not give him the trouble to ask you for it. When you have done all these, then your friendship unites with his friendship and his friendship with yours. Another tradition has reported that Mu'alla said that the Imam added, 'When you have done that, your friendship is then joined to his; and his friendship is joined to Allah's.'
