Hadith is about Reciting Superiority of Poor Muslims

Sahl bin Sa`d As-Sa`idi RA reported: A man passed by the Prophet (sallallaahu ’alayhi wa sallam), so he asked a man who was sitting near him, "What is your opinion about this man?'' That man replied: "He is one of the noblest men. By Allah he is certainly a proper person for (a girl) being given in marriage if he seeks to marry, and his recommendation is fit to be accepted if he recommends". Messenger of Allah (sallallaahu ’alayhi wa sallam) remained silent. Then another man passed. Messenger of Allah (sallallaahu ’alayhi wa sallam) enquired, "What is your opinion about this man?'' He replied: "O Messenger of Allah, he is one of the poor Muslims. He is not a proper person (for a girl) to be given in marriage to, and his recommendation would not be accepted if he makes one; if he speaks, he is not to be listened to.'' Messenger of Allah (sallallaahu ’alayhi wa sallam) said, "He is better than the former by earthfuls". (Bukhari and Muslim)
