勸發菩提心集 3.145

3.145

非田不應施有七：一乞求者極大暴惡，曾為怨害歸依怨害而有所求；二勸為善事終不能得；三心壞染污為染污事而有乞求；四為損惱而有乞求；五乞求者或自是魔，或魔所魅非處乞求；六乞求父母或復隨一非所施物；七能為無義。

There are seven [types of] non-fields to which one should not give: (1) when the petitioner is extremely violent and evil, having formerly been an enemy who has sought refuge with an enemy and makes a request; (2) when one can never succeed in exhorting them to do wholesome deeds; (3) when their mind is corrupted and defiled, and they make a request for the sake of defiled matters; (4) when they make a request for the sake of causing harm or affliction; (5) when the petitioner is either Māra himself, or possessed by Māra, and makes an improper request; (6) when they beg for one's parents, or any other thing that is not an object for giving; (7) when it would bring about what is pointless.
