This isn't necessarily an experience from the PD's that I have been to, but it is an interesting hadith to think about when we make charitable efforts such as PD:
The Holy Prophet (p.b.u.h.) said:
"When charity (alms) is delivered out of the hand of its owner, it (the thing being given) says five things: 'At first I was perishing and you gave me life; I was insignificant and you made me great; I was an enemy and you turned me into a friend; you used to protect me then but now I will protect you up to the Day of Resurrection'."
