PROPHET MUHAMMAD (ﷺ) said:
You gain no victory or livelihood except through (the blessings and invocations of) the poor amongst you.

PROPHET MUHAMMAD (ﷺ) said:
Seek for me weak persons, for you are provided means of sustenance and helped through your weaklings.

PROPHET MUHAMMAD (ﷺ) said:
The one who looks after a widow or a poor person is:
1) Like a Mujahid (warrior) who fights for Allah's Cause, or
2) Like him who performs prayers all the night and
3) Fasts all the day.

PROPHET MUHAMMAD (ﷺ) said:
'Allah, Glorified and Exalted is He, will say on the Day of Resurrection:
"O son of Adam, I fell SICK and you did not visit Me."
He will say: "O Lord, how could I visit You when You are the Lord of the Worlds?"
He (Allah) will say: "Did you not know that My slave so and-so was sick, but you did not visit him? Do you not know that if you had visited him you would have found Me with him?
O son of Adam, I asked you for food and you did not feed Me."
He will say: "O Lord, how could I feed You when You are the Lord of the Worlds?"
He (Allah) said: "Did you not know that My slave so-and-so asked you for FOOD, but you did not feed him? Do you not know that if you had fed him, you would have found that with Me?
O son of Adam, I asked you for WATER and you did not give Me to ink."
He will say: "O Lord, how could I give you to drink when You are the Lord of the Worlds?"
He (Allah) will say: "My slave so-and-so asked you for water, and you did not give him to drink. If you had given him to drink you would have found that with Me."
