One criteria for charity giving

[Charity is] for the poor who have been restricted for the cause of Allah, unable to move about in the land. An ignorant [person] would think them self-sufficient because of their restraint, but you will know them by their [characteristic] sign. They do not ask people persistently [or at all]. And whatever you spend of good – indeed, Allah is Knowing of it.
Al Quran 2:273



There is no good in secret counsels except!

There is no good in most of their secret counsels except (in his) who enjoins charity or goodness or reconciliation between people;and whoever does this seeking Allah’s pleasure, We will give him a mighty reward.

[Al-Quran 4:114
