I wrote to Abu Ja'far Al-Thani (as), peace be upon him, asking about a piece of land that my grandfather had endowed for the needy among the descendants of so-and-so, the man who united the tribe. However, they are numerous and scattered across different lands, while the descendants of the one who made the endowment are in severe need. They asked me to allocate the endowment specifically to them, excluding the other descendants of the man who united the tribe. Imam (as) replied: "You mentioned the land that your grandfather endowed for the poor among the descendants of so-and-so. It is designated for those who are present in the town where the endowment exists, and you are not permitted to seek out those who are absent."
