If you come across a poor person at a gathering or you were invited by a poor person at home or at work, do not look down upon him or her because you consider them poor. Poverty is not a defect or a fault to be ashamed of, while lack of kindness and generosity is.
Remember that the poor will enter paradise much before the rich- “The poor of the Muhajireen will enter Paradise five hundred years ahead of the rich of the Muhajireen.” (Saheeh al-Jaami’ 4/90, no.4104).
Majority of the people in paradise will be the poor-Prophet (s.a.w) said, “I stood by the gate of Paradise and saw that the majority of those who entered were the poor and wretched. The rich [Muslims] were detained while the people of Hell were ordered to be taken to Hell”. [Sahih Al Bukhari]
Treat poor companions or guests with honor and respect. Be pleasant while talking to them, using the best language. Again, poverty is not a vice. Many of the poor are more honorable than the wealthy, and many who are penniless are preferred to the rich.
