“Once a man said to abu Ja’far (a.s.), ‘I have a certain amount of property in the mountains from which I receive three thousand dirham profit every year. I spend two thousand dirham for my family and one thousand dirham for charity every year.’ Abu Ja’far (a.s.), then said, ‘If the two thousand is enough for all of their needs for the year, you have been considerate for yourself, had good opportunity to have the right guidance. You have executed a plan for yourself in your lifetime which is like what one plans in his will.’”
