Don't turn your eyes away from someone begging, they live among us, they are like us HUMANS, they need what we need.. yet we keep blindly ignoring them and pass them!! Beware sometimes Allah subhanhu wa tala'a send you the needy as a test to see if you worthy to increase His blessings... listen to the poor.
The Prophet (saw) said:"Be merciful to those on the earth, so the One above the heavens will be merciful to you." [At-Tabarani and al-Hakim]
