Abu Abdillah, Ja’far ibn Muhammad, peace be upon both told me: "Be just with people in your personal matters and let them have a share in your wealth. Choose for them what you choose for yourself! And remember Allah constantly; never be lazy nor feel bored; surely, that is what my father taught me and that is what his father counseled him. Similarly, if you feel lazy about the late night prayers, you will not be able to fulfil to Allah His right. And if you are bored and discontented, you will not be able to fulfil anyone’s obligation. Always be truthful, guarding against sins and paying back that which you hold in trust. And do not fail to fulfil a promise when you make one."
