Sahih Bukhari Volume 007, Book 062, Hadith Number 028.
Narrated By Sahl : A man passed by Allah's Apostle and Allah s Apostle asked (his companions) "What do you say about this (man)?" They replied "If he asks for a lady's hand, he ought to be given her in marriage; and if he intercedes (for someone) his intercessor should be accepted; and if he speaks, he should be listened to." Allah's Apostle kept silent, and then a man from among the poor Muslims passed by, an Allah's Apostle asked (them) "What do you say about this man?" They replied, "If he asks for a lady's hand in marriage he does not deserve to be married, and he intercedes (for someone), his intercession should not be accepted; And if he speaks, he should not be listened to.' Allah's Apostle said, "This poor man is better than so many of the first as filling the earth."
