5.29

又像法決疑經云。若檀越設食。並請眾僧。遣人防門。遮障比丘及諸老病貧窮乞人。不聽入會。徒喪飲食了無善分。

Furthermore, the Xiangfa jueyi jing states: "If a dānapati prepares food and invites the Saṅgha, but posts people to guard the gate, barring bhikṣus, the elderly, the sick, the poor, and beggars, not allowing them into the assembly, he wastes food and drink in vain, having no share of goodness whatsoever."
